Hiroshima Synchrotron Radiation Center, March 8-9, 2018

The International Review Committee (IRC) met at Hiroshima University March 8-9, 2018, to review thescientific programs at HiSOR. The IRC had been provided with extensive background material before themeeting and complementary information during the review. The HiSOR management and scientists were mosthelpful in answering questions during the review and the IRC commends the Director for a very professionallyorganized meeting. The IRC also wants to express its gratitude for the hospitality it was shown throughout its
stay at HiSOR.
The review was in conjunction with the 22nd Hiroshima International Symposium on Synchrotron Radiation.
This gave the IRC the opportunity to listen to a number of excellent presentations by HiSOR scientists andinteract with young scientists at a poster session that gave a survey of recent research activities. The posters werevery informative and consistently of excellent quality.
In the opening address to the Symposium the Vice President of Hiroshima University, Professor Yamamoto,underlined the important role HiSOR has for research and education at this University. The IRC was very
impressed by the commitment the University Administration has to the success of HiSOR. The Director of
HiSOR, Professor Shimada, gave a most impressive summary of the research activities during the last five years.
The scientific productivity is remarkable with a large number of publications, a significant fraction in the mostdistinguished peer-reviewed physics, chemistry and biology journals. HiSOR has been highly successful in
implementation of the “Joint Usage” concept, in which HiSOR staff scientists are directly involved in thecollaborative research triggered by external users. The IRC congratulates HiSOR to this success and strongly
recommends that the “Joint Usage” model is continued. Collaborations with world-renowned international
researchers account for about 25% of the activities and are an important aspect of the operation of HiSOR. The
IRC is of the opinion that HiSOR is in an excellent position to further expand these activities in attracting
world-leading researchers. The IRC finds that HiSOR is doing exceptionally well in continued upgrades andmaintenance of the accelerator systems, the beamlines and the end-stations; in particular considering therelatively modest staff and operating cost.
Professor Shimada emphasized five focused research areas for HiSOR:•

High-Resolution Photoemission Spectroscopy for Electronic Structure Analysis•

Spin-Resolved Photoemission for Spin Structure Analysis•

Soft X-Ray MCD of Surface Nano Structures•VUV Circular Dichroism Spectroscopy of Biomolecules•

Light Sources Accelerators and Insertion Devices

High-Resolution Photoemission Spectroscopy for Electronic Structure Analysis
Photoemission is a major activity at HiSOR and Dr. Eike Schwier gave an extensive overview of presentresearch and future directions.

Polarization dependent ARPES. - The predictive use of dipole selection rules depending on polarization ofincident photons is an effective tool to study multiband systems such as pnictide high-Tc superconductors or
topological systems. This experimental methodology has presently been introduced in a wide use at HiSOR
based on two different polarization control schemes, rotation of the ARPES analysis chamber (BL-1) or the useof variably polarizing APPLE-II undulator (BL-9A and B). A particular attention is paid to "clean" experimental
geometry allowing reliable use of the polarization effects. This methodological advance at the HiSOR beamlines
is supported by the off-line µ-ARPES facility where polarization control of the laser radiation is achieved bywave plates. The power of the polarization control methodology in application to multiband systems is
confirmed by a number of pioneering scientific cases. The IRC commends HiSOR for these developments.

Improvement of spatial selectivity. - The IRC highly appreciates the recent effort to reduce spot size ofsynchrotron radiation of the sample. The present typical spot size of the order of a few hundreds of µm seems
actually the main bottleneck to limit instrumental quality of synchrotron light delivered by HiSOR, in particular
because crystals of many interesting materials typically appear consisting of small domains with their typicaldimensions of the order of a few tens of µm and less. After careful investigation of all options, the HiSOR
scientists are advancing an idea of using innovative VUV-range elliptic capillary mirrors (Sigray Inc.) which are
expected to reduce the spot size down to 75x30 µm2 (BL-1). A large practical advantage of this option is its
moderate budget (of the order of 100 KEuro). In addition to the spatial selectivity, the spot size reduction willmuch increase angular resolution of the ARPES experiment. The IRC highly recommends pursuing this
instrumental upgrade route. The research with high spatial selectivity is presently supported by the off-lineµ-ARPES facility.

Sample environment. - A functional and user-friendly sample environment is a critical part of the spectroscopic
experiment. The HiSOR's recent advances in this instrumental direction include (1) high-precision 6-axis
goniometric manipulator; (2) cryogenic sample cooling down to 12K at BL-1 and even to 7K at BL-9A; (3)high-temperature (>2000K) sample annealing; (4) surface doping by alkali evaporation during the ARPES
experiment. The IRC highly appreciated the HiSOR's constant effort in the sample environment functionality.

Off-line ARPES facilities. – The IRC fully supports the intensive development of the off-line laser and UV-lamp
ARPES facilities which allow exhaustive preliminary sample characterization and thus most efficient use of thesynchrotron beamtime. Furthermore, the µ-ARPES facility allows experiments at extremely high spatial, energy
and angular resolution complementary to those with the HiSOR light.

Molecular and organic systems. - Molecules adsorbed on crystalline surfaces have recently attracted muchattention due to their new emerging functionalities such as realization of single-molecule magnets. Organic
systems including perovskites have recently demonstrated their potential, for example, in solar energy

conversion. ARPES experiments on such systems are often hindered by radiation damage. The low energy andpresently large spot size of the HiSOR's photon beam, minimizing the radiation damage, make ARPES studies ofthe molecular and organic systems, in the view of the IRC, a promising research field at HiSOR.

Spin-Resolved Photoemission for Spin Structure Analysis
Equipped with VLEED that has an efficiency 100 times higher than the conventional Mott spin polarimeterand synchrotron radiation with adjustable photon energy and polarization, HiSOR is one of the most active
centers for SARPES research in the world with top level equipment and scientific achievements. In his talk Dr.
Taichi Okuda gave a status report of this facility.
The VLEED spin-resolved ARPES system has demonstrated an energy resolution of ΔE ≤ 10 meV, anangular resolution of 0.4˚ and the capability of 3D spin vector analysis, which are among the highest resolutions
reached in spin-resolved ARPES in the world and enables precise spin-resolved measurements that require highenergy and angular resolutions, such as topological insulators and Wyle semimetals. In fact, the IRC takes noteand congratulates HiSOR to a system that has produced highly original results and landmark publications in the
direct measurements of spin-split electronic states of topological materials and other novel quantum materials.
The versatile sample facilities permit preparation of a variety of samples efficiently and ensure timely
responses to new research trends. As pointed out earlier by the IRC the Joint Usage/Research programs are agreat asset at HiSOR and enable external users to get efficient support from staff members to acquire
high-quality data efficiently.
Due to the synergistic effects of world-class facilities and excellent staff support, the number of users,
especially from abroad, is rapidly growing and half of the proposals are now from international participation.
The IRC considers the shortage of beamtime as a serious problem for HiSOR to maintain and further enhance its
world-leading status in a fast growing and very competitive research field.
The IRC strongly supports the future plan of HiSOR to develop the laser SARPES system and themultichannel VLEED spin polarimeter.

Soft X-Ray MCD of Surface Nano Structures
Dr. Masahiro Sawada reported on the XMCD station on BL-14, which is specialized for in-situ synchrotron
radiation analysis accompanied by sample synthesis with a focus on studies of magnetic nanostructures. This
combination is an important research direction in materials science. HiSOR has been very successful in theimplementation to studies of magnetic nanostructures, and in particular to magnetic states of artificiallycontrolled materials. The IRC observes and commends HiSOR that the basic construction of the XMCD station
has been completed. Some very impressive research results have been achieved, in several cases in collaboration
with outside user groups.
The IRC fully agrees with several of the proposed upgrades listed in the section “perspective” for thisexperimental station, for instance extension of the operational temperature range and upgrade of the magnet
system to allow stronger magnetic fields. The scientific justifications are strong. A limitation to liquid nitrogentemperature excludes studies of ferromagnetic materials with a lower Curie temperature and studies of smallmagnetic clusters on surfaces. The IRC recommends the addition of a superconducting magnet or a high field
electromagnet to open up studies of hard magnetic samples and /or measurements along hard magnetic axis. The
IRC further suggests installation of a magnetic field sensor close to the sample, allowing to avoid problems
related to the residual magnetization of the electromagnetic core (particularly important for samples with low
coercivity). An additional improvement would be to add a sensitive fluorescence detector for measurements on
insulating samples.
The system is well equipped with automation that is very important for efficient operation by the users. The
IRC recommends that the automation with programmable sequences of the geometry settings should also include
adjustments along the z-axis, M(H). The existing STM system with in-situ characterization of the sample is avery important asset and in many cases provides a unique capability. The IRC encourages HiSOR to include inits future plans additional characterization tools as electron diffraction for structural analysis and an ion
scattering spectrometer, and/or an SEM column, for surface analysis. The sample preparation is an important
aspect and, in addition to existing tools, the IRC recommends monitoring of the substrate temperature during thedeposition process. This would enhance the structural quality of the deposited films and precision of their
thickness measurements.
So far studies have been focused on samples that require UHV conditions. Since not all studies require
UHV, the IRC recommends that HiSOR considers the implementation of a low vacuum/atmospheric pressure
sample chamber that can be separated from the UHV beamline with a silicon nitride membrane. The inclusion of
the photon-in-photon-out techniques, as is required for this environment, would extend the studies to new classesof magnetic materials, including certain multilayer structures. The IRC is also positive to include reflectivity
measurements is a method to probe the dielectric tensor.

VUV-CD Spectroscopy of Biomaterials
BL-12 demonstrated by Dr. Koichi Matsuo is proof of a well functioning beamline. The field of interest
encompasses the biophysical and structural biology. BL-12 offers a continuous operation during the working
hours, allowing circular (CD) and linear (LD) dichroism as well as absorption spectroscopy. The
vacuum-ultraviolet (VUV) CD spectrophotometer at BL-12 extends the CD spectra to the VUV region down to
170 nm for aqueous solutions and to 140nm for films. Low noise, low sample consumption (microliter range)and quick data acquisition provide structural information, which is unattainable with conventional CD
instruments. Applications include membrane proteins, saccharides, nucleotides and disordered protein structure
analysis, as well as protein-protein interactions, protein-nucleotide interactions and protein lipid interactions.
Other activities of great value complementing these spectroscopic measurements, are principal component
analysis, molecular dynamics and bioinformatics. (Peer reviewed publications and citation numbers, are proof ofreliability) The group of Dr. K. Matsuo has recently been joined by a Dr. Y. Izumi, which certainly increases thepossibilities for exploring the beamline as well as accommodating and helping users more efficiently. The IRC
was impressed by the present output and usage of the VUV-CD. Five posters of BL-12 trained students, havebeen presented and two of them were rewarded with the poster prize amidst an otherwise very physics driven
poster session with 24 eligible students’ posters.

External users have collected data during the meeting. Dr. Frank Wien has himself reviewed the beamline
and assured the IRC of reproducibility of standards and compliance of results and reproducibility between
European Synchrotron Circular Dichroism stations and BL-12.
Developments in place such as the sublimation chamber, for thin film preparations of organic chiralmolecules, the installation of a mirco-focusing optic (Schwarzschild) and time resolved devices, including
microfluidic continuous flow and stopped flow set-ups are certainly a very good addition to the present
possibilities and should in future attract even more users and students. If one recommendation should be given to
improve the current setup, then it would be the installation of an automated temperature stepping mode for CD
and absorption spectroscopy. For instance, this would allow for thermal stability analysis and thermodynamic
studies in combination with calorimetric assays.
Further developments which have been discussed with the beamline staff include the development andimplementation of a CCD camera for VUV-CD imaging, and the long-term development and design of a novel
Vortex light producing undulator producing circular left and right polarised light. The IRC strongly supports theinvestigations into these novel developments to pave the way for a new HiSOR light source.
In a conclusion, important improvements over the past 10 years have been made BL-12 has become a very
productive tool for structural biology, glyco-biology and in a more general way for chiral macro-molecularstudies where other techniques fail due to size of the molecules or their complicated flexible structures.

Light Sources Accelerators and Insertion Devices
Dr. Keigo Kawase introduced HiSOR and presented the development by the minute accelerator staff at the
HiSOR Light Source. The International Review Committee points out that with the present level of staffs (3persons in total), a minimum has been reached! Even then, the staff has made several interesting developments
as presented at the relevant accelerator conferences.
One area has been the study of new low-emittance lattices to be used in a future HiSOR facility. This has
included the so-called “torus-knot” design, but also designs based on the MAX-3 lattice and the ASTRID2
machine. Further developments of these lattices, to result in a detailed design of the future HiSOR machine, canonly be strongly encouraged, as this eventually will be needed and will constitute the basis for the futureaccelerator. Such a study should include a parameter list, and should also develop into the specifications of thevarious accelerator components in the new source.
Another study performed by the present HiSOR accelerator staff is the study of advanced undulators likequasi-periodic APPLE-II and Knot-APPLE undulators generating Orbital Angular Momentum undulator
radiation. Such studies will also be relevant for insertion devices in a future HiSOR light source.
Collaborations with other accelerator facilities like KEK and UVSOR were mentioned, and theInternational Review Committee strongly suggests such continuations and further collaborations in the future.
This will also be important in preparation for the future HiSOR facility.
General comments and recommendations:
There is presently limited operation time of the present HiSOR facility, two injections per weekday, which
is limited by man-power. Numerous requests for an extended operational beamtime have appeared from the usercommunity over time, and the IRC can only recommend such an extension if at all possible, but clearly notneglecting safety and man-power limitations.
The IRC strongly suggests the development of an almost “diffraction-limited” low-emittance lattice toreplace the present HiSOR light source, possibly based on the highly successful upgrade of ASTRID, the
HiSOR’s low-energy sister facility. Such a facility should include several insertion-devices (more than 4), top-up
injection, 24/7 operation and could deliver beams, which would be orders of magnitude smaller in all dimensions
than the present facility. Although, the present research performed at HiSOR is indeed very good, a new facility
would expand the quality and quantity of the present HiSOR research facility tremendously way into the2030’ies.

Introduction
The Hiroshima Synchrotron Radiation Center, HiSOR, is the only one synchrotron radiation facility that is
attached to a national university in Japan. It was established in 1996, as part of the academic policies of theJapanese government. The mission of HiSOR is to promote advanced research in the field of condensed matterphysics using synchrotron radiation in the ultraviolet and soft x-ray range, as well as to develop human resources.
In 2010, HiSOR was authorized as a “Joint Usage / Research Center” by the Ministry of Education, Culture,
Sports, Science and Technology (MEXT). As a result of extensive research activities in collaboration withresearchers from inside and outside of Japan, HiSOR was graded “A” for the 1st term-end evaluation in 2015 by
the MEXT. In 2016, the authorization as the Joint Usage / Research Center was extended for 6 more years. The
mid-term evaluation is planned in 2018.
According to this authorization, HiSOR is focusing on the following researches:
1. Researches on quasiparticles by ultrahigh resolution photoemission spectroscopy
2. Researches on spin structures by spin- and angle-resolved photoemission spectroscopy
3. Structural analysis of biomolecules in solution by VUV-CD
4. In situ fabrication and characterization of magnetic nanostructure by SXMCD
5. R&D for a compact low-emittance light source
In this context the International Review Committee (IRC) was charged to evaluate the scientific research
activities at HiSOR. Below is a detailed self-assessment of the five research areas listed above by the responsible
HiSOR scientists.

Research Areas
1-1. Eectronic structure analysis (BL-1, BL-9A, laser PES)
Current Status
Angle-resolved photoemission spectroscopy (ARPES) is a powerful tool to directly reveal the electronic
states in solids, such as energy band dispersions and Fermi surfaces. Since the initial stage of HiSOR, we havepromoted high-resolution ARPES in the ultraviolet and soft-x-ray region at the undulator beamlines BL-9A(hν=5~35 eV) and BL-1 (hν=22~360 eV). Recently, in order to improve spatial resolution as well as energy andangular resolution, we introduced two VUV laser systems (hν=5.90-6.49 eV) to HiSOR; one providing a Laserbeam of around 300 µm size to the BL-9A end-station, and the other, a Laser beam with a spot size as low as 3
µm to a newly commissioned offline µ-LaserARPES machine [H. Iwasawa et al., Ultramicroscopy 182, 85(2017); refer as #1].
ARPES with low energy photons (hν<~10 eV) is effective to examine the isotope [H. Iwasawa et al., Phys.
Rev. Lett. 101, 157005 (2008)] and many-body [2012-(3), 2013-(26) (List of publications)] effects in cuprates,
as well as detailed examination of the Rashba splitting in the surface state on Cu(110) [2014-(34)], while higher
photon energies are essential to investigate the kz (i.e. bulk) dispersion of electronic bands and matrix element
effects, and distinguish surface-derived states. A combination of the two photon energy ranges allows fordetailed spectral analysis in wide momentum and energy spaces.
Recently, it has become indispensable to utilize the polarization dependence of the matrix elements tostudy multiple Fermi-surface systems such as iron-based superconductor [Y. Zhang et al., Phys. Rev. B 83,
054510 (2011)], topological surface states on W(110) [2012-(35)] and novel layered superconductor [2015-(23)].
In order to utilize the polarization of incident photons, we have constructed a rotatable ARPES system at BL-1
[H. Iwasawa et al., J. Synchrotron Rad. 24, 836 (2017)] and installed a variably polarizing undulator(quasi-periodic APPLE-II) for BL-9A and 9B [S. Sasaki et al., Proceedings of IPAC2012, 729 (2012)]. At theµ-LaserARPES machine, a combination of wave plates allows for full control of the light polarization between
linear and fully circular polarized photons [#1]. Utilizing the ultimate purity of linear polarization andcontinuous rotation of the detection plane with respect to the electric field vector, detailed examinations of thephotoemission intensity of the Dirac cone in graphene could be performed at BL-1 [2015-(30)].
These days, topological materials have attracted much interests, and many photon-energy-dependent
ARPES measurements have been performed at BL-1 to reveal the three-dimensional electronic structures ofthese materials. In these cases, flat cleaving surfaces were often smaller than the present beam size (900 (H) µm
× 200 (V) µm). This in turn reduced the amount of successful measurements on such systems due to the large
number of cleaving attempts necessary to obtain a large enough surface, leading to a strong demand to reduce
spot size on the sample.
Precise momentum mapping of the band dispersion is crucial when performing high resolution ARPES
experiments. To that end all the manipulators are controlled by an in-house LabVIEW software with arbitrary

choices of mapping dimensions [#1, H. Iwasawa et al., J. Synchrotron Rad. 24, 836 (2017), refer as #2]. Now,
one can automatically perform ARPES mappings using arbitrary combinations of directions (polar, azimuth, tilt,
x,y,z). To improve the spatial resolution, we have upgraded the low-temperature 6 axes manipulator of BL-9A
and installed a “nano-stage” manipulator at the µ-LaserARPES [#1,#2]. The nano-stage in combination with themicron-sized Laser spot is crucial to the performance of the machine as it enables users to reproduce sample
positions with sub-micron precision and perform detailed spatial mappings with high lateral resolution.
To perform various advanced experiments at the beamlines, sample preparation and characterization are
also important. On the three machines, standard characterization methods (LEED and Auger electron
spectroscopy) are available. For sample preparation Ar Ion sputtering and annealing (direct current as well as
electron bombardment) can be performed [#1,#2]. A newly designed preparation chamber manipulator headallows for annealing temperatures higher than 2000 K with room for additional flashing of the sample.
At BL-1 and the µ-LaserARPES, an alkaline metal evaporator has been installed in the main chambers,
allowing the evaporation in coincidence with ARPES measurements. The possibility to monitor the evolution of
the surface doping has been highly appreciated by users [2014-(2)] as it allows not only fine control over thedoping state, but also resolves the coverage dependent electronic structure in greater detail.
Using the ARPES system with variable polarized low energy photons (5-35 eV) provided by the APPLE-II
undulator, users can investigate fine details of the electronic structure. Due to continued efforts to improve thebeamline optics, and specifically the monochromator stability, photons with linewidths below 1 meV can beprovided for energies below 10 eV [M. Arita et al., Phys. Rev. B 77, 205117 (2008)]. To improve the ARPES
capabilities further, we have installed a fully motorized 6-axes goniometer (temperature range: 12-370 K,
azimuth angle rage: ±65˚, tilt angle range: -25˚ to +50˚). This enables us to measure Fermi surface maps over awide momentum range via tilt or azimuth rotations. The new goniometer is also effective to measure band
dispersions along high-symmetry lines for small Fermi surfaces located close to the Γ point of the surface
Brillouin zone. To make use of the high energy resolution provided by the beamline, a cryo-shield has been
installed that allows for cooling of the sample to temperatures below 6 K. However, in its current stage it also
produces energy and lateral resolution broadening as a tradeoff due to vibrations, and possibly external fields. To
increase user experimental time, BL-9A is also equipped with the aforementioned UV laser as well as a highintensity Xe-lamp. Representative results obtained at BL-9A over the last 5 years include the elucidation of thechiral texture of the orbital angular moment in Bi2Se3 [2012-(34)], the observation of the topological surface
states in Sb2Te3 [2015-(32)] and the first clarification of the electronic structures in the novel superconductor
IrTe2 [D. Ootsuk et al., J. Phys. Soc. Jpn. 86, 123704 (2017)].
Starting in 2014 we developed and commissioned the stand-alone µ-LaserARPES machine at HiSOR [#1].
Within the first year we were able to achieve ultimate energy resolution (260 µeV at 7.2 K with 0.75 meV and
1.5 meV resolution as common user choices during experiments) and started establishing a user community.
Focusing on achieving ultimate angle as well as spatial resolution we upgraded the manipulator stage("nano-stage") and replaced pinhole apertures used for reducing the spot size with focusing optics. This let us
achieve ultimate angle (undetectable Gaussian broadening at Lorentzian FWHM of 0.0033 Å-1 in Bi-2212) andspatial resolution at the same time. We have installed an optical monitoring system (spatial resolution ~14 µm)

for sample position adjustments. Based on the results from the µ-LaserARPES system, we have found thelinewidths of ARPES spectra can be drastically improved depending on the measurement positions even forlayered samples having a good cleavage plane and a seemingly well cleaved surface.
At the moment, users have to choose one of the two manipulators; one reaching 5 K with narrower angularrange able to probe superconducting transitions, and the other reaching 11 K with wider angular range. It would
be desirable to either have the low-temperature manipulator reach more competitive temperatures (2-3 K) or
enhance its angular range.
In 2017 we installed a Xe-lamp to allow for measurements of the valence band at the Brillouin zone
boundary. We also connected a preparation chamber for non-cleaving samples. The preparation chamber is
independent from the main transfer route allowing for the measurement of cleaving samples while moredemanding sample preparation can take place in the preparation chamber.
So far the µ-LaserARPES system has been successfully used to investigate, among other things, c-fhybridization effects in Ce-based single crystals [2015-(31)], temperature dependent band renormalization in
FeSe superconductors [M. D. Watson et al., J. Phys. Soc. Jpn. 86, 053703 (2017)] and quasi 1-dimensionalcharge-density wave compounds [16BG039 (List of proposals)] as well as novel Dirac materials [16BG039] anda number of graduate student projects focusing on high energy resolution of the BCS gap of superconducting
materials.

Evaluation
The rotation of the BL-1 main chamber around the light incidence allows for a unique setup where thedegree of linear polarization remains at 100% all the time. Such a polarization dependent ARPES measurement
enables users to disentangle multi-band system based on the dipole selection rule. Furthermore, this system has
been proven useful to extract orbital textures by continuously rotating the incident electric-field vector withrespect to the detection plane [2015-(30)].
The high-resolution variably polarized low-energy photons from the APPLE-II undulator at BL-9A, in
combination with the available offline sources, provide an excellent environment to investigate fine details in theelectronic structure near the Fermi level. The installation of the fully motorized 6-axes goniometer and thecontrol software allows high-quality ARPES measurement in momentum space.
The recently commissioned µ-LaserARPES machine has already proven to be a highly competitive setup.
It is now getting attention from different groups inside and outside of japan for its attractive combination of
spatial, angular and energy resolution.

Perspective
The experience gained from past and future upgrades of the three machines will be transferred to thebeamlines of HiSOR-II. It is expected that orders of magnitude more efficient ARPES measurements and/or
ARPES with improved spatial resolution of ~1 µm will be possible at the new synchrotron ring. At HiSOR-II
more detailed investigations of the electronic structures can be performed which are indispensable to further
fundamental understanding of various transport and magnetic properties of solids.

Keeping in mind the current trend of community demands, as well as the future upgrade of the synchrotron
towards a low emittance source, it is important to focus on two main points of improvement. On one hand, basedon the impressive results from the µ-LaserARPES system, it is of crucial importance to reduce the spot size fromits current size (900 (H) µm × 200 (V) µm) to at least below 100 µm to increase the surface selectivity as well as
the angular resolution and stay internationally competitive.
It is highly recommended to promote the project to introduce focusing optics to BL-1 and BL-9A which iscurrently under way. The first upgrade is scheduled to be at BL-1 during the fiscal year 2018. The upgrade of themanipulator to allow for higher lateral precision and control of the measurement position is also recommended.
At the same time a deflector type analyzer upgrade should be considered allowing for the effortless mapping of
Fermi surfaces without the demand to correct the position of the beam during the otherwise necessary sample
rotations. A deflector type analyzer would also allow to probe orbital textures in more detail due to thepossibility to counter rotations of the sample surface with a deflector angle allowing for different combinationsof mirror-plane and plane-of-incidence geometries while detecting the same electron bands in k-space. A future
upgrade of such a deflector type analyzer to integrate a 3D VLEED-type spin detector should also be considered.
This would lead to a unique situation at BL-1 where high spatial and angular resolution with surface and kz
sensitive excitation energies are combined with resolution of the spin (VLEED) and ultimate resolution of orbital
textures. The latter is being possible by the rotatable analyzer system, which allows to keep 100% purity ofpolarization between p- and s-polarization a feature setting apart BL-1 from other ARPES beamlines around theworld.
At BL-9A, similar to the situation at BL-1, one of the user’s most frequent requests is the reduction of thephoton spot-size. To meet this demand, it is highly recommended to introduce a high magnification ellipsoidal
mirror and spatial filter to the main chamber which can reduce the beam size down to ~30 µm. This upgrade willallow the measurements of small domain samples or rough cleaved 3-dimensional sample surfaces. Anotherdemand from many users is the addition of an automated photon energy control system that changes the
monochromator and undulator gap automatically. This, together with the 6-axes goniometer would allow users to
map the 3-dimensional momentum space in a convenient fashion.
Finally, to advance the capabilities to measure at low temperatures with very high energy, angular andspatial resolutions it is necessary to improve the design of the goniometer to reduce the residual magnetic fields
in the chamber and improve the thermal radiation shields to reduce mechanical vibrations. To that end a
low-vibration coupling to the cryo-shield should be installed and crucial parts of the manipulator exchanged with
non-magnetic materials.
In its current stage the µ-LaserARPES machine is highly competitive and allows for the production ofstate-of-the-art results. To stay ahead, it is recommended to extend its capability to access ultra-low temperatures(T~2-3K). One of the options is an installation of a low-vibration cryo-shieled in combination with a new
goniometer. It has been shown that such a setup can achieve temperatures below 3 K while retaining therotational degrees of freedom [M. Hoesch et al., Rev. Sci. Instrum. 88, 013106 (2017)].
At the same time, it would be interesting to add the capabilities to resolve the valence band and outer partsof the Brillouin zone (UPS) and/or the chemical state (XPS) of a sample on a comparable length scale as theLaser does. A focused x-ray source could also be used to obtain structural information via x-ray photoelectron
diffraction (XPD). To achieve micro focused He or Xe light a mirror/monochromator setup would be necessary
in combination with a capillary type focusing mirror [Capillary focussing morrors by Sigray Inc.
(http://www.sigray.com/), refer as #3]. In such a case spot sizes of some 10 µm would be available. For micro
focused XPS/XPD the main chamber design would need to be changed to accommodate existing monochromatorand x-ray sources and a capillary type optics [#3] would again be employed to achieve micron order spot sizes.

1-2. Spin structure analysis (BL-9B, laser spin-ARPES)
Current Status
This research division conducts research on quantum spin physical properties of materials by spin- andangle-resolved photoelectron spectroscopy.
So far the staff of HiSOR have developed and being improving spin- and angle-resolved photoemission
spectroscopy (spin-resolved ARPES) endstation equipped with a very low energy electron diffraction (VLEED)
type spin polarimeter. Since the efficiency of VLEED polarimeter is about 100 times higher than theconventional Mott spin detecotor, higher resolution measurement (ΔE ≤ 10 meV, Δk = 1 × 10-2 Å-1 @ hν = 21eV) in shorter measurement time has been realized [T. Okuda et al., Rev. Sci. Instrum. 87, 103302, (2011)]. In
2013, a second VLEED spin polarimeter, that was set orthogonally to the previous one, was installed at 90 ˚ toenable complete determination of 3-dimensional spin vectors (Sx, Sy, Sz) [2015-(5) (List of publications)]. Also,
for accurate Fermi surface measurements, a high precision low temperature 6-axes goniometer is available. At
the beamline polarization dependence of incident light (left / right circular polarized / horizontal / verticalpolarized) measurement can be done by the APPLE II type variable polarization undulator. The available photon
energy of the beamline is hν = 16 to 300 eV.
Because of the high performance of the end-station about 90 collaborative researches (half of which isinternational collaboration) have been done in the last 6 years and many important results have been obtained as
described below. Discovery of ideal topological insulators, Bi2Te2Se and Bi2Te2Se, with high spin polarization(paper No. 2012-(38) in the publication list, Top 10% papers, Press releases (3), Newspaper reporting (5)),
elucidation of the polarization and excitation energy dependence of the spin polarization of the prototypical
topological insulator Bi2Se3 [2014-(40), Top 10% papers], the first observation of the Valay Spin Structure of
MoS2 [2014-(28), Top 1% papers], discovery of the existence of topological surface state in superconductor
β-PdBi2 [2014-(16), Top 10% papers], experimental verification that YbB12 is a topological Kondo insulator[2016-(15)], the observation of hidden spin polarized states in the novel superconductor LaOFBiS2 [S. L. Wu etal., Nature Commun. 8, 1919 (2017)] and so on (2 more Top 10% papers).
In addition to the beamline BL-9B, a new spin-ARPES system using vacuum ultraviolet 6 eV laser light is
now under commissioning for the purposes of further expansion of collaborative researches and for R&D aiming
for usage of the 3rd generation light source in the future. The electron analyzer with special electron deflector(Scienta-Omicron DA-30) that enables to do Fermi surface mapping or angle resolved measurement without
using manipulator rotation. By utilizing laser light, not only resulting in improvement of energy andwavenumber resolution, but will also open up research on micron samples or multi-domain samples by using thehighly focused laser beam. In addition, research using variable polarization properties will be useful to study
detailed polarization dependence in spin-ARPES measurement.
Furthermore, a multi-channel spin detector that can improve the efficiency of spin-detection more than
1000 times higher than the present system is now under construction.

Evaluation
The importance of high-performance spin-resolved ARPES experiments and of maintaining its
performance and stable operation should be emphasized, given the scarcity of places in the world where
high-resolution spin-resolved ARPES experiments using SR light can be conducted. The strategy of having one
system running with a well-established and reliably working system is advantageous, while developing inparallel a new spin-resolved ARPES experiment utilizing laser light source which opens new possibilities in the
spin-resolved ARPES measurement. Furthermore, the successive efforts of the staff to improve the efficiency
and resolution of the spin-ARPES measurement by developing the multichannel spin detector are very importantfor maintaining a world-leading position in the future.
The VLEED spin-resolved ARPES system has demonstrated an improvement of the spin detection
sensitivity by more than 100 times compared to conventional spin detectors and has also achieved an energy
resolution of ΔE ≤ 10 meV and an angle resolution of 0.4˚ or better, which are among the highest resolutions
reached in spin-resolved ARPES in the world. It currently enables precise spin-resolved measurements formaterials or surfaces that require high energy and angular resolutions, such as topological insulators or Wylesemimetals.
Actually, the system has produced highly original results in the direct measurement of novel spin splitting
electronic states of topological materials. High spin sensitivity of the VLEED spin detector and possible
high-resolution measurement, as well as the capability of 3D spin vector analysis, are really helpful to obtainreliable data and the successful measurements of valley electronic system (MoS2), topological Kondo insulator(YbB12), hidden spin polarization in novel superconductor (LaOFBiS2) are good examples.
In order to fully exploit the unique features of these spin-resolved ARPES experiments, versatile sample
preparation facilities are needed. In the sample preparation chamber of the systems, it is possible to prepare andevaluate clean surfaces of single crystalline metals, nanostructures, and bulk samples including layered materials
without changing the experiment setup. These features permit to prepare a variety of samples efficiently and torespond quickly to new research trends in this fast-moving field. For example, the high-temperature annealing
system can heat samples up to 2000˚C or more and clean the surfaces of tungsten and other metals, which has
proven very useful. Clean tungsten surfaces are often used as substrates for the growth of ultrathin metal films.
The Joint Usage/Research programs using the spin-resolved ARPES instruments always involve HiSOR
staff members. This means that users can acquire high-quality data efficiently from the first day even if it is thefirst visit for them. Due to the uniqueness and the complexity of the equipment, there is no other way to operate.
By the synergistic effects of these facts, the number of users especially from abroad are rapidly growing
recently. It is noteworthy that half of the proposals are now from abroad. However, on the other hand, this fact

makes the securement of beamtimes for HiSOR staff very difficult. The introduction of a laser source anddevelopment of a new and much more efficient multichannel spin detector are meaningful in this respect. But
even so, the beamtime is absolutely too scarce compared to other facilities.
The synchrotron radiation is currently unavailable at night and weekend in HiSOR. An intense He lamp has
therefore been set up to enable night-time measurements. While this definitely helps to increase the utilizationand efficiency of the facility in preparing and characterizing samples and, in some cases also in obtaining
high-resolution spin-resolved ARPES measurements, it would be highly desirable to be able to run experiments
also during the night and/or weekend with synchrotron radiation.

Perspective
The recent boom in spintronics and topological insulators research is raising demands for spin-resolved
ARPES measurements. Given the global scarcity of spin-resolved ARPES instruments in operation, HiSOR canhelp to meet the demand by operating both systems, i.e. systems at SR beamline and with a laser source. With
these resources HiSOR can play a prominent role in this research field. The demand is especially high forspin-resolved ARPES measurements using high-brilliance synchrotron radiation sources. Spin-polarized surface
states on topological insulators are often located near bulk bands, hence high energy and angular resolutions are
required and the possibility to tune the photon energy is crucial. Although the new laser SARPES system will be
helpful the use of synchrotron radiation is essential if the characteristics of the high-resolution spin-resolved
ARPES systems are to be exploited to the fullest extent. Currently, companies like VG Scienta and SPECS are
bringing commercial instruments on the market, but the development of the VLEED type spin detector and also
multichannel spin detector at HiSOR will keep this facility ahead of the field.
Staff people at HiSOR have a long-term experience with designing and operating spin-resolved
photoemission experiments. The institution is thus in an excellent position to develop a "multichannel spin
detector”. This would represent one of the world's most ingenious measurement systems for spin-resolved
ARPES to dramatically enhance the energy and angle resolution, and potentially to introduce the possibility ofultrafast temporal resolution.
It is strongly desired that HiSOR engages in all these efforts in the future to enhance its capabilities andcreate the world’s finest environment for the most advanced spin-resolved ARPES experiments, making
synchrotron radiation available 24/7, and provide a stable supply of user beam time.

1-3. Nanomaterial analysis (BL-14)
Current Status
The BL-14 beamline has been utilized for some types of absorption spectroscopy experiments in the soft
X-ray region between 400 and 1200eV, including the main technique of soft X-ray magnetic circular dichroism(XMCD) measurements. The targets of the XMCD experiments are magnetic nanostructured materials grown on
many kinds of substrates, whose samples are fabricated by epitaxial method, controlled monatomically and wellcharacterized in crystallinity and morphology by electron reflection and STM measurement. The XMCD

experimental system consists of a SR measurement chamber and a suite of interconnected UHV chambers for thein-situ sample fabrication and analyses, where the samples can be transferred into its neighbor chamber without
braking UHV condition.
Sample growth method is well established in the sample fabrication chamber, supported by capabilities ofmonatomic layer control using real-time RHEED oscillation measurement and deposition method of
wedge-shaped over-layers with fine thickness control and sub-monolayer precision. The sample temperature andpressure of reactant gases are also monitored and controlled, which is effective in fabrication process of somekinds of films or interfaces. Fabricated magnetic nanostructures are quickly transferred into the part of XMCD
spectrometer, and their native magnetic properties are investigated without an influence of oxidation or surface
pollution.
STM system is also incorporated into the XMCD station, which enables in-situ observation of atomic
arrangement or microscopic morphology in angstrom scale. The STM component is installed as a part of theinterconnected chambers through a UHV pass-way with vibration insulation. Atomic resolution images havebeen successfully confirmed for a reconstructed surface of Si(111) at the beamline site. Combination
experiments between STM observation and XMCD measurement are effectively carried out for magnetic
clusters on a single crystal surface, where relation between the size of magnetic cluster and their magnetic
properties can be discussed.
In the main part of the XMCD spectrometer, the samples can be exposed to circular polarized synchrotron
radiation and magnetic field supplied by a sliding permanent magnet and an electromagnet system. The
electromagnet system can control the amplitude of variable field and direction of the field to the sample surfaces,
supporting element specific magnetic hysteresis loop measurements and angle dependence analyses of orbital
magnetic moment.

Evaluation
The HiSOR BL-14 has completed the construction of a combined system for material fabrication, structural
information analysis and atomic-specific magnetometory using circularly polarized synchrotron radiation, whose
experiment system is based on a philosophy that SR measurements should be carried out in-situ for artificial
surface structures fabricated under good quality control at the beamline site. In-situ experiments have beensuccessful to a large degree, especially for ultrathin magnetic films, whose results are supported by the control ofdeposition and growth by on-line RHEED oscillations, the surface chemical analysis by AES, measurement of
the long range symmetry and domain size by LEED, the fine morphological analysis by STM, and the XMCD
measurements with quantitatively reliable analysis. Fine interface control in layered structures, monatomic
thickness control of ultarathin films, and lateral size control of surface clusters are well regulated in the context
of the sample fabrication toward development of functional layered materials in technological applications.
Performed quantitative analysis of local magnetic moment and element-specific hysteresis loop measurements
are quite significant for the artificial structures that include magnetic elements.
After the recent upgrade of the electromagnet environment, the direction of magnetic field can be freely
selected to the sample crystal axis. This improvement is significant, because a data set of XMCD spectra for asample magnetized along sample normal and in-plane direction provides parallel and perpendicular components
of local magnetic moments to the surface. The measurement method of angle-dependent XMCD will contributeto studies of anisotropic orbital magnetic moments existing in two-dimensional magnetic layered structures.
Continuous measurement of STM and XMCD for an identical sample is very attractive for researchers in
the fields of surface and interface science. The system integration of STM environment into the beamline stationand the successful model study on magnetic surface clusters are worthy of special mention. It is recommended toopen the STM system to world-wide users in order to expand the capability of combining experiment of STM
and XMCD, if additional man-power for user support becomes available.
The system configuration of the soft X-ray beamline BL14 has provided a sophisticated experimental
station for researches and developments of magnetic artificial structures. The strategy to complete materials
synthesis, structural analysis and magnetic measurement on-site at a SR beamline, is challenging and important
for researches based on a concept of material design. It is appreciated that some efforts along the strategy havebeen succeeded at BL14 for magnetic nanostructures related to functional materials. Although the performanceof the photon beam is limited due to an older generation SR facility, there still remains some points to be
improved at the BL14 system, for example, enhancement of magnetic field and temperature control below liquid
nitrogen temperature in the XMCD measurement.

Perspective
The concept to build SR experimental stations for sample synthesis and fine analysis is one of important
ideas for material science, which is followed by the continuous efforts at BL-14 in the research field of magnetic
nanostructures. The basic construction of the XMCD station has been finished and some good cases ofutilization have been successfully established including collaborative works with outside user groups, leading todeep understanding of magnetic states of artificially controlled materials on an atomic scale.
To enhance the potentiality of the beamline station, improvement of the XMCD spectrometer should be
required from some technical viewpoints; an extension of the operation temperature range, an enhancement of
the magnet system to apply stronger magnetic field and a device for high throughput operation. The coolingcondition for the XMCD measurement is limited down to liquid nitrogen temperature at present, which excludes
coverage of ferromagnetic compounds with lower Curie temperature or small magnetic clusters on surfaces. A
superconducting magnet or high field electro-magnet is recommended for taking stable spectra of hard magnetic
samples or measurements along hard magnetic axis. The system upgrade supporting lower temperature andhigher magnetic field, is effective for the BL-14 station to widen a scope of target materials and to attract
researchers in various fields. An automatic drive of sample manipulation and rotary stages for angle settings ofsample and magnet, enable time-efficient and easy operation for users. Automation with programmable sequenceof geometry settings and spectra measurements is a good way to enhance the productivity.
As to the sample preparation segment of the XMCD station, a sophisticated structural analyses isrecommended for fabricated samples in-situ. An advanced analysis of electron diffraction provides 3D structural
information at the interfaces of layered samples, which is crucial for artificial films related to spintronics devices.

Additional surface analysis tools of ion scattering spectrometer or SEM column in the UHV may benefit surface
analysis, which give us complementary information to the existing STM system.
The XMCD station at BL-14 is specialized for in-situ SR analysis accompanied by sample synthesis at thesame site, which should be continuously upgraded and utilized by the expertise of internal staff and input fromoutside users. On the other hand, easy-to-use environment for soft x-ray spectroscopy is also required forbeginners and light users, especially, those who do not demand UHV condition. Since UHV condition is notnecessarily required as long as electron detection methods are avoided in the spectroscopy experiment, it is agood idea to adopt photon-in-photon-out methods in a low-vacuum/atmospheric pressure chamber that can beseparated from the UHV beamline by silicon nitride membrane. Reflectivity measurement in the soft X-ray
region is effective to probe the dielectric tensor in materials and to search structural models of multilayers. The
XMCD effect is also found in the reflectivity spectra with greater signal than in conventional absorption spectra,
which has an advantage to magnetic materials with poor conductivity.

1-4. Circular dichroism of biomaterials (BL-12)
Current Status
Circular dichroism (CD) a spectroscopy technique, which is very sensitive to the steric structures of
optically active materials and widely used for structural analysis of biomaterials such as proteins, sugars, andnucleic acids because it can be applied to a wide range of biomaterial samples under various
solvent/experimental conditions. A vacuum-ultraviolet (VUV) CD spectrophotometer can extend the CD spectrato the VUV region below 190 nm by using synchrotron radiation (SR) and thereby provide novel structural
information that is unobtainable in conventional CD instruments [2013-(5) (List of publications)]. HiSOR was
one of the world's first SR facilities, which successfully developed a VUVCD beamline. Now the SR-VUVCD
beamlines are under operation in seven SR facilities (ISA in Denmark, BSRF in China, NSRRC in Taiwan,
BESSY2 in Germany, Diamond Light Source in United Kingdom, ANKA in Germany, and SOLEIL in France).
Further, Elettra in Italy and LNLS in Brazil are planning to construct new SR-VUVCD beamlines.
The HiSOR-VUVCD spectrophotometer is composed of an optical system that generates left- andright-circularly polarized light at 50 kHz and a detection system that consists of two photomultipliers and alock-in amplifier. This spectrophotometer has the capacity to obtain the CD signal with high precision down to
120 nm by connecting these two systems using an optical servo control technique. This spectrophotometer was
installed into BL-15 first. Afterward, to improve precision and speed for the VUVCD measurements, HiSOR
built a new Wadsworth normal incident monochromator (BL-12 since 2013) as a light source for VUVCD,
which made SR light available at a photon flux of 5×1010 photons/sec/mm2/100 mA at 190 nm (at the sample
position).
Recently, a Schwarzschild focus mirror was set up to reduce the size of SR light in the spectrophotometerbecause the SR beam size of BL-12 was 6 × 6 mm at the sample position. This focusing mirror provided 20 × 20
µm beam size and allowed the reduction of sample volume needed for one measurement (20 µl → 2 µl),
allowing to measure rare samples such as membrane proteins. The software for CD measurements was upgradedand allows now the high-tension voltage (HTV) of the photomultiplier or the linear dichroism (LD) to bemonitored simultaneously. The HTV is used for obtaining the absorbance spectra of the samples and the LD
measurement is particularly valuable for obtaining the information of biomaterial orientations [2016-(30)].
Structural analysis of proteins and sugars are now routinely measured, combining leading-edge computational
techniques such as bioinformatics, molecular dynamics (MD) simulation, and time-dependent density functional(TDDFT) methods which substantially increased the structural information content from VUVCD spectra. The
combination of these methods reveales the pairwise relationships between structures and CD of monosaccharides
in solution [2012-(13)] and also realized the analysis of intermolecular structures of amyloid fibrils [2014-(11)].
Further, these techniques are used for analyzing the solution structures of histone proteins relating to various cellfunctions such as DNA damage repair [Y. Izumi et al., J. Radiat. Res. 58, 59 (2017)].

Evaluation
The VUVCD spectrophotometer can extend the CD spectra down to 140 nm in the VUV region, giving agreat advantage in the structural analysis of biomaterials. To enhance this advantage, many important upgrades
were conducted last six years. The most important upgrade was the construction of new beamline (BL-12),
which successfully increased the photon flux, thereby enhancing the quality and efficiency of measurements.
The developments of spectral analysis using TDDFT and MD could disclose new structural information ofproteins and sugars in solution. Focusing system using a Schwarzschild focus mirror realized the deduction ofsample volume for one CD measurement. These considerable efforts should be highly evaluated.

Perspective
BL-12 can provide high photon flux with the VUVCD instrument without any damages to the solution
samples. Hence, the optimizations of parameters of M3 mirror and the exchange of coating materials on grating
mirror from MgF2 to Ru could be possible to further increase the photon flux and enhance the efficiency ofmeasurements. Most important point is that more than 15 years have passed since the VUVCD equipment was
first developed. It is highly desirable that a next-generation VUVCD device that incorporates leading-edge
optical and detection systems is constructed. At present, the CD spectra are measured using single detector byscanning the monochromatic SR light from 4 to 10 eV. Then, using new technology such as a multichannel
detector or CCD camera, the efficiency of the VUVCD measurement would be extremely enhanced.
At present, the study using VUVCD spectroscopy mainly focus on the static structures of biomaterials, andthen these targets should be replaced with the dynamic structures such as the protein folding and the structuralchange of protein inducing by the interaction with other biomaterials. To conduct these experiments, small sizeof SR beam is necessary. The focusing system of SR light recently constructed could make micro size SR beam
and allow to observe the structural change of biomaterials at the level of millisecond or microsecond. Further,
this focusing system could also lead the construction of screening CD system in which the CD spectra of various
samples with different solvent conditions on the microplate are automatically measured. This measurement
technique would expand the usage of VUVCD tool to various fields such as CD imaging of biomaterials.

1-5. Light source accelerators and insertion devices
Current Status
The light source accelerator system at the Hiroshima Synchrotron Radiation Center (HSRC) consists of a
150 MeV injector microtron, a beam transport line, and a racetrack type storage ring. This system is called
HiSOR (Hiroshima Synchrotron Orbital Radiation). The circumference of this ring is 22 m, and the bending
radius is 0.87 m in the normal conducting bending magnet with the magnetic field of 2.7 T. Stored electron beamenergy is 700 MeV, and synchrotron radiation having the critical energy of 873 eV from two 180-degree bending
magnets can be extracted from 14 photon beam ports. There are two straight sections between these magnets andtwo undulators are installed at the straight sections. At the present, one of them is a linear undulator (2.4 m long,
57 mm period) that generates 26 – 300 eV linearly polarized radiation. Another one is the quasi-periodic APPLE
II type undulator (1.8 m long, 78 mm period).
The HiSOR ring has been successfully operated and has been delivering stable photon beams for HiSOR
users since 1996. Operation hours exceed 2,000 hours in each year, and users’ operation hours are about 1,600
hours. The machine is running 11 hours a day (with 2 injections) and 4 days a week. Monday is research formaintenance. The machine startup in the morning takes only 30 minutes. Close to turn-key operation is possible
for normal use.
Because of the long operation from 1996, some problems have occurred in the last 5 years. One of the mostserious problems was the water leakage from an absorber for the synchrotron radiation inside the vacuum
chamber of the storage ring in the middle of 2012. Due to this problem, the machine time for users was lost for
400 hours in this year. After this problem, the vacuum was poor of an extended period of time. Thus, the initial
beam current was limited to 250 mA because of radiation safety regulations. The complete recovery of thistrouble had been finished in 2015. As the result, the machine time for user operation in 2016 has been recovered
to the level of before 2011 and the initial stored current is recovered to 300 mA. Although it is not so serious,
there are problems of wave leakage in several places, and thus, the replacements and repairments will besystematically continued.
In order to extend the life of the HiSOR operation for the next decade, the power supplies for the magnet
system and the accelerating cavity have been replaced during the last 5 years. The power supplies of the bendingand quadrupole magnets for the storage ring was replaced in 2013, and those for the microtron were replaced in
2014. The amplifier for the accelerating cavity for the storage ring was replaced from the vacuum-tube type tothe solid-state type in 2017. The replacement of the klystron amplifier for the microtron is planned in the next
fiscal year. As the results of these upgrades, the reliability for the long-term operation of the HiSOR issignificantly improved.
Although the 24-hour operation has been requested from various users for a long time, it is difficult tosatisfy due to the lack of technicians.
Before previous international reviewing in 2012, the design study for the upgrade of the light source wasbased on the design of MAX-III lattice of MAX-lab in Lund, Sweden. It is based on combined function magnets
for bending and focusing, has 4 insertions and 4 short straight sections. It has a circumference of 40 m and could

be accommodated on the open space of the HSRC. The design value of the equilibrium emittance is 14 nmrad.
Because of the short lifetime of the stored beam (below 3 hours), the 3 Hz top up operation is planned.
From 2010, a new design of the storage ring has been vigorously studied. It is based on the Torus-knot
concept. It has a lattice structure where the beam orbit closes after multiple turns in the storage ring. By applying
this new concept, the orbit length of the beam can be three times longer than the ring perimeter. In addition, the15-m-diameter ring equipped with 11 bending magnets has 11 long (3.6 m) straight sections capable for
installing insertion devices and other necessary accelerator components. During the last 6 years, detailed studies
has been done on this design addressing a multi-bend lattice, magnet parameters to optimize the emittance anddynamic aperture.
It is noteworthy that the collaborative work with UVSOR at Okazaki has started for studies of orbital
angular momentum of the synchrotron radiation from tandem undulators. These studies are expanded now to thelarge collaborating research field for the light vortex.

Evaluation
Although the accelerator system of HiSOR has been in place for 20 years, it still operates well and can be
maintained to accommodate the state-of-the-art synchrotron radiation experiments. It is noteworthy that the
turn-key mode of operation is reliable. As a consequence of the recent upgrades of the power supply system, thereliability and long-term maintainability is improved. In order to satisfy the user request to make 24-hour
operation, it is necessary to employ additional technical staff.
As part of the upgrading plan for HiSOR, the design study for a new accelerator system was conceptuallycompleted at the time of previous international review in 2012. It is a low emittance storage ring with the energyof 700 MeV, the circumference of 38 m and the emittance of 14 nmrad. The design is based on the MAX-III
storage ring at MAX lab, Sweden. In addition, there has been recent progress for a completely new design,
namely a storage ring based on the concept of a torus knot. This work has much originality and impact in the
research field of accelerator sciences.
The studies of new types of undulator such as the knot-APPLE undulator and quasi-periodic undulator are
undertaken in detail. These studies have also contributed to the high-level educational environments for graduate
students.

Perspective
HiSOR is expected to continue its successful operation for several more years at its present performance,
because of the recent and planned upgrades of the accelerator components.
For a long time, 24-hour operation is desired from a lot of users. It is, however, difficult to realize theirrequest because of the lack of operators. The employment of additional technical staff is strongly desired.
Regarding the upgrading plan for the next light source, it is also recommended that comparisons should bemade between designs obtained so far as well as including a design from the ASTRID2 facility in Aarhus,
Denmark. These design studies should be undertaken in parallel with the tasks of the daily maintenance andlong-term upgrade plan for the existing accelerator systems.
