REPORT:THE FIRST MEETING OF
THE KEK SCIENCE ADVISORY COMMITTEEMarch 23-24, 2019
KKR Hotel Tokyo1. Executive Summary
The first meeting of the KEK Science Advisory Committee took place at KKR Hotel Tokyo on March 23
and 24, 2019. The program of presentations can be found in Appendix A. The membership of the SAC isprovided in Appendix B. The presentations to the SAC were well-focused and informative, highlighting
notable history, recent activities and plans for the future. KEK performs a diverse research program
covering particle physics, nuclear physics, cosmology, materials science, and life science. KEK’sachievements are very impressive on all fronts.
KEK holds a forefront scientific position with strong efforts in education, dissemination and outreach.
KEK runs and develops world-leading electron-based and proton-based accelerator facilities at TsukubaCampus and Tokai Campus, respectively. Using beams of photons, electrons, positrons, neutrinos, muons,
neutrons, pions, kaons, and protons from these facilities, KEK pursues fundamental laws of nature and theorigin of function of materials. More than seven thousand scientists from all over the world use KEK’s
cutting-edge accelerator-based facilities each year. KEK develops the next generation of accelerator
technologies for a wide range of science and technology and collaborates with industry on research aimed
at developing useful products. KEK also strengthens its portfolio by partnering in high-priority facilities
hosted elsewhere, including LHC/ATLAS experiment at CERN, KISS at RIKEN, UCN at TRIUMF, and
POLABEAR-2 at Atacama.
At this meeting, the SAC was asked to focus on the followings:• Review the Updated KEK Roadmap, and give your comments and suggestions. Do you endorseit?
• In the KEK-PIP, our next priority is muon g-2/EDM experiment and upgrade of the J-PARC
Hadron Hall, and we will begin funding discussion with the MEXT. Give your comments andsuggestions.
• It is urgent for us to further activate discussions on the future light source replacing the PF/PFAR. Review the plan given by the IMSS.
• Any remarks/suggestions/warnings/criticism on the four major research projects and research
program in the four institutes will be highly appreciated.
The SAC strongly endorses KEK’s decision on near-term priorities (the muon g-2/EDM experiment, theupgrade of the J-PARC Hadron Hall, and the upgrade of the Photon Factory), and the updated KEK
roadmap. The KEK leadership should be congratulated for establishing outstanding near- and longer-term
strategies and for producing the implementation plan. Specific comments and/or recommendations are
discussed in Chapters 3 and 4.
The KEK leadership team recognizes a big gender gap in scientific and technical staff. This gap issignificantly larger than that in other countries. The SAC encourages the KEK team to develop programs
that could help to reduce this gap. The SAC hopes that KEK becomes an exemplary institution in this
aspect.
2. Major research projects and research program in the four institutions
2.1 J-PARC
J-PARC is a unique facility supporting many fields of science research and technological projects byproviding different types of particle beams produced via a primary high intensity proton beam. The
facility is undergoing several upgrades and it will be crucial to balance between providing sufficient beam1

time for the experiments and improving the performances of the different parts of the facility devoted to
the nuclear and particle physics and to material science.
The accelerator neutrino experiment T2K has discovered the transition of muon neutrino to electron
neutrino and found an indication of CP violation. This is based on a 490 kW proton beam. These
achievements open a possibility of detecting the neutrino CP violation, which will be one of the mostimportant discoveries in particle physics in the coming decade. To keep a leading role in accelerator
neutrino physics by reaching the goal to detect CP violation to 3s, and to match up the future Hyper-K
detector, sufficient beam time should be maintained, and the upgrade plan to increase the proton beam
power to 750 kW and further to 1.3 MW should be carried out. Comparing with the investments on theHyper-K detector, it is worthwhile to pursue goals higher than 750 kW and 1.3 MW on the beam
improvement, which seems possible according to current excellent performance.
The nuclear and hadron physics program has been very successful in the recent years confirming the key
player role of Japan in the study of hyper-nuclei and in the precision measurements of rare decays ofneutral kaon and muon. The short-term upgrades will open opportunities, including an opportunity in the
study of hot dense matter testing finite temperature QCD. In addition, the ongoing R&D for themeasurement of the anomalous magnetic moment and electric dipole moment of the muon is very
promising.
2.2 SuperKEKB
Together with the BABAR experiment at SLAC, the Belle experiment at KEK observed a long-awaited
CP violation in the B0 →J/yKS decays in 2001, which resulted in the Nobel Prize to be awarded to
Kobayashi and Maskawa in 2008. After the end of data taking in 2010 with a total luminosity of 1 ab-1,
the storage rings of the KEKB accelerator and the spectrometer of the Belle detector went through major
upgrades, and the SuperKEKB and the Belle II were born.
The first operation of the SuperKEKB after the upgrade took place about three years ago, without the
Belle II detector in place. During the second operation of the SuperKEKB one year ago, where the BelleII detector was installed together with a provisional vertex detector, the machine achieved a luminosity of
5×1033 cm-2s-1. The installation of the accelerator upgrades in the final focus and interaction region wascompleted with Phase 2 beam commissioning in 2018. During this Phase 2 period, the numerous
measures were taken to suppress electron-cloud build-up (a major problem at the KEKB) and this newprocess is proven to be effective up to more than half the design bunch-train current.
The experiment has just started the first physics run with a nearly full Belle II detector. Although thevertex detector is equipped with one pixel layer, rather than the designed two, and some other detector
components are not yet completely functional, the experiment should be able to perform physics analysis.
The collaboration is fully committed to obtain some physics results for conferences in the summer 2019.
It should be noted that the Belle II collaboration is a truly international collaboration, consisting of morethan 900 people from 26 countries.
2.3 Photon Factory
The Photon Factory is probably the oldest major light source operating in the world today. Strategic
upgrades carried out 23 and 14 years ago, together with the addition of PF-AR, have ensured it hasremained relevant to generations of scientific users from Japan and throughout the world. This isevidenced by a comparatively small change of ~15% in users and an oversubscribed proposal system,
despite a 40% reduction in user operating hours over the past few years. Scientific outputs (6002

papers/annum) remain at a very high standard and the science that is carried is world leading in someareas. Developing industry collaborations primarily around crystallographic services is very encouraging.
A combination of ageing infrastructure and increased competition from newer facilities calls for its futureplan. Further renovation and/or a complete rebuild are up for consideration as is the impact of this within
the changing Japanese light source ecosystem. The PF leadership assessed the situation and produced aplan. The PF leadership is congratulated for instituting this timely evaluation.
2.4 HL-LHC
Having collaborated very successfully in experiments at CERN for many years prior to the LHC, Japan
became the first non-CERN member state who joined the LHC. KEK has played significant roles inconstruction of the LHC accelerator, and construction and operation of the ATLAS detector. KEK
scientists have been involved in high profile analyses. Recent examples include the Higgs-top coupling
and SUSY searches. KEK is one of the core Japanese institutes in the ATLAS experiment providing astrong leadership and coordination.
For the High-Lum LHC, MEXT approved the Japanese contribution. KEK will provide beam separation
dipole magnets. The 1st and 2nd model magnets were built and tested successfully. The next step is mass
production of the magnets. Concerning the detector upgrade, the KEK team has been playing a key role inthe silicon tracker, the muon detector, and the trigger system. Efforts appear to be well planned withappropriate infrastructure. The detector upgrade schedule is tight and continuous monitoring is needed.
2.5 Institute of Particle and Nuclear Studies
The Institute of Particle and Nuclear Studies (IPNS) has been leading competitive projects such as BelleII and T2K, which attract international interests and researchers. The IPNS has been also promoting many
cutting-edge experiments in a variety of fields such as hyper nuclear and hadron physics, muon and kaon
physics, and astro-particle physics in addition to theory and computational physics. Furthermore, the
IPNS plays a very important role in ATLAS at CERN, RIBF at RIKEN with their own developed facility
KISS, TUCAN at TRIUMF, and ILC, collaborating with world-wide top institutes. Bottom-up approachin a flat organization of the IPNS has been successful for promoting diverse projects with rather limited
recourses.
Since many of these projects are in the production phase, stable operation of KEK and J-PARC
accelerators is most important. In order to sustain the high activity and leadership of the IPNS in the
future, coherent and strategic prioritization of projects and periodic reviews are necessary.
2.6 Institute of Materials Structure Science
The IMSS provides an excellent particle beam platform complex for the domestic and international
scientific community. The combination of synchrotron radiation, neutron, muon, and slow positronprovided by the KEK platform plays a unique role for the cutting-edge studies in the diverse fields ofmaterials and life science. The research programs at the IMSS are well set up for full and effective
utilization of the facilities, and keeping the facilities at the highest standard is critical for its success. The
quality of scientific output by the IMSS is very impressive.
The shortage of staff and operational budget for the neutron and muon beamlines at the J-PARC is a
critical barrier achieving the full scientific performance anticipated for the state-of-art beamlines. Thisrequires an immediate attention, followed by a proper action. Planning for a new synchrotron radiation
source to replace current sources at KEK is in progress. The position of this planned new SR source3among the existing domestic and international SR sources needs to be carefully thought through to makeit a key player in the coming many years.
2.7 Accelerator Laboratory
The Accelerator Laboratory (ACCL) consists of seven divisions with about 200 staff members in total. It
is in charge of all KEK accelerator activities, especially J-PARC, SuperKEKB, e+/e- linacs, PF, PF-AR,
cERL, ILC R&D and accelerator theory. Over the past years the ACCL accomplished several importantmilestones: (1) the completion of the SuperKEKB construction and a promising rapid start of the phase 3
beam commissioning; (2) establishing the routine e+/e- linac operation for injection into four rings, withvarying bunch charge and energy pulse by pulse; (3) the demonstration of the design beam power of 1
MW in the J-PARC RCS; (4) a world record slow extraction efficiency better than 99.5% from the MR;(5) the definition of a clear J-PARC roadmap to achieve 750 kW in fast extraction by 2022 and 1.3 MW
by 2028; (6) the introduction of full-energy top-up injection at PF-AR; and (7) the development of a PF
upgrade plan based on a new low-emittance optics.
On 1 April 2019, the ACCL will be reorganized so as to include a new center for applied SC accelerators,
while the number of divisions will be reduced to six. The ACCL personnel is fully committed, without
any margin or any free resources. The SAC is concerned that the retiring rate (11 ACCL scientists andtwo engineers in March 2019, corresponding to more than 6% of the total staff) significantly exceeds therecruitment rate of new staff (three per year). Maintaining key accelerator expertise and preserving a
critical number of competent and dynamic experts will be important for accomplishing the challenging
performance goals set for the next ten years.
2.8 Applied Research Laboratory
The Applied Research Laboratory (ARL) consists of four centers totaling about 80 staff members:
Radiation Science, Computing Research, Cryogenics Science, and Mechanical Engineering. The ARL
provides technical support to KEK on radiation activity management, supercomputing and IT services,cryogen supply and cryogenic system operations, and mechanical construction and engineering. The ARL
also conducts research and development activities including radiation transport codes development, gridtechnology, multi-core CPU computing, DAQ development, and superconducting magnet for future
projects.
It is highly appropriate that the ARL provides technical support while each individual project team takes
ownership and responsibility in radiation safety including hazard analysis, mitigation, and personnel
training. Centralizing services like radiation transport calculation, computation and IT, controls,
cryogenics, mechanical and electrical engineering offers the advantage of conformance to establishedstandards and regulations, quality assurance, and work efficiency. On the other hand, design andconstruction of a complex device requires tight integration and interface. For example, design andfabrication of superconducting RF cryomodules requires close integration of SRF, cryogenics, andmechanical engineering. Close coordination and corporation between different KEK laboratories areneeded, which can both be highly rewarding and challenging.
3. Recommendations on Updated KEK Roadmap
3.1 Particle and Nuclear Physics
A "Higgs Factory" capable of precision studies of the Higgs boson, such as the ILC, is strongly endorsedby the international high energy physics community. Japanese physicists have been playing a leading rolein linear-collider R&D for the past 30 years. Their contributions were essential for reaching today’s level4

of technical maturity. KEK is well positioned to lead the effort for realizing the ILC hosted in Japan as aninternational project in collaboration with the worldwide HEP community.
KEK is a leading member of the large Japanese experimental group in ATLAS at CERN, and contributed
to the array of important physics analyses, software and hardware developments. Its mission, as well as
the participation of the high luminosity upgrade, should be strongly supported.
The SuperKEKB accelerator has just begun it Phase 3 operation with successful collisions, and the record
high luminosity in the collider history is expected to reach in the next years to come. The BelleII experiment will study the decays of B mesons and tau leptons to unprecedented precisions, and willreach a tremendous sensitivity to probe new physics beyond the Standard Model in the flavor sector. JPARC has been prolific and a variety of experiments on flavor physics, neutrino physics, hadron physics
and nuclear physics is being successfully carried out.
There are vibrant activities taking place at the KEK Theory Center, including healthy publications,organizing topical workshops, hosting visitors, and training a large number of postdocs and students.
Topics covered at the Theory Center include particle physics phenomenology, nuclear physics, hadron
physics and lattice QCD, astro-physics and cosmology, as well as formal physics of string and quantum
field theory. At the flagship lab with world-leading experimental endeavor, interactions and mutual
supports between the theory center and experimental groups should be further strengthened
The Computation Division at KEK takes on the challenge and performs well. While entering the “Big
Data” era, new challenges and opportunities may emerge. Beyond the routine computation needs at KEK,
it would be prudent for KEK to make a systematic effort to systematically engage the new issues such as
deep learning.
3.2 Material structure science and structural biology
We applaud the demand for and productivity of the KEK programs at both PF and MLF (J-PARC). Thereis clear scientific excellence across the materials science and structural biology portfolio, as well as strong
examples of industrial relevance. At the next meeting, we would like KEK to clarify where believes it
holds, or could hold, a leadership position in materials science or structural biology.
We commend the idea of developing a matrix of instrumentation at the PF. The same approach mightwell succeed across the whole neutron and muon instruments at J-PARC (including the JAEA andCROSS instruments). But it is difficult to be science-driven, with the present level of resourcing, andwithout being embedded in a broader multi-purpose laboratory (like HZB, CEA/CNRS in France or the
DOE labs in the USA). It would therefore be worth benchmarking KEK’s approach against similar userfocused institutes.
KEK performs industrial research. Its significant role in industry and society demonstrates an important,but often unseen, impact on our everyday lives. It could also bring revenue, resulting in increase of thebeam time in the future.
The national landscape has become very different now for synchrotrons and the other quantum beamprobes. KEK/J-PARC has a leadership/monopoly position for neutrons, muons and positrons, whereas it
has to compete with SPring-8, and in the future with SLIT-J, in synchrotron science.

53.3 Accelerator development
The SAC commends the creation of a new center for applied SC accelerators, which will leverage theexisting cERL and STF infrastructures, in a consortium with industry and partners, for various importantsocietal applications (medical radioisotope production, miniaturization of semiconductor devices, etc.).
The SAC notes that the planned continued advancement of superconducting RF technology and of
improved systems for high-power RF generation will be important not only for the ILC, but also for any
future large accelerator project.
Accelerator expertise and infrastructure have been accumulated over decades with successful design,
construction and operation of the TRISTAN and the KEKB. They have been and will be key to thesuccess of KEK. The SAC notes that core accelerator experts who worked on the TRISTAN and the
KEKB have already retired or will soon retire, long before SuperKEKB is pushed to its peak
performance. KEK succession planning and recruitment policy should anticipate the retirements ofessential personnel such that accelerator expertise will be transmitted to the next generation of personnel
at KEK. Part of the aging accelerator infrastructure at KEK requires consolidation to ensure a high beam
availability for stable SuperKEKB and PF/PF-AR operation over the coming decade(s). A comprehensive
risk analysis would guide the prioritization and allocation of funds with a limited spending profile.
A roadmap for subject matter expert growth and infrastructure build-up could be essential for KEK’s
strategic planning. For example, a major undertaking like the ILC may require a team of several hundredsof experts to conduct design, prototyping, and construction. In-house infrastructure for some critical steps
is likely necessary, as shown by other projects (e.g. mass assembly of cryomodule for the X-FEL in
Europe, and SRF cavity final processing and cryomodule assembly for FRIB at Michigan State
University). Such build-ups of expertise and infrastructure may take 5 to 10 years. The SAC encourages
KEK to include this aspect in its strategic roadmap. The in-house plant to develop mass production
techniques for SRF cavity fabrication is an excellent step in this direction.
The small but strong accelerator theory group is almost unique in the world nowadays. Its efforts will beessential for the success of the ongoing and future accelerator projects. For a world-leading accelerator
institute like KEK, it is important to reserve some capacity to work beyond routinely planned scope and tosupport the accelerator R&D for future projects. A long-term perspective might also help attract brightyoung scientists.
4. Recommendations on the next steps
4.1 Muon g-2/EDM
The SAC recommends that KEK moves forward with the muon g-2/EDM project at J-PARC. The
experiment has the goal to measure the muon's magnetic moment anomaly and the electric dipole momentwith ultra-high precision with a novel approach compared to previous muon g-2 experiments. It makes
use of a high-quality muon beam with small transverse emittance, obtained from the acceleration of asource of polarized thermal muons, which will be stored in a ring of smaller diameter. This is an
important measurement since the present result is not in complete agreement with the Standard Model. It
also involves a wide field of novel expertise and developments ranging from material science for an
efficient Muonium production target, laser physics for its ionization and accelerator physics for muon
acceleration. These muons open themselves unique opportunities in other research fields because they canbe used to develop a muon microscope for material and life science research.
The development and operation of an efficient Muonium source and of a long-term stable and powerfullaser system to generate Lyman-alpha light for the photoionization of thermal Muonium is crucial for a6

successful experiment since the uncertainty of the measurement of the muon magnetic anomaly isdominated by statistics. Important progress has been made in the past years in the development andoperation of the laser system, yet it appears that there are remaining issues concerning laser reliability andachievable intensity. The SAC is pleased to hear that various alternative solutions concerning thegeneration of thermal muons are being worked out in detail. The performance and the availability of a key
ceramic optical component of the laser system should be demonstrated.
4.2 J-PARC Hadron Hall extension
The J-PARC Hadron Hall extension is an important upgrade with the goal to expand the unique capability
in nuclear and hadron physics and thus to enhance further the leadership of Japan in this sector. New andwell-focused experiments are planned addressing open questions concerning nuclear structure withstrangeness, hot dense nuclear matter and the search of flavor changing rare processes. The world-wide
position of the foreseen experimental program is unique either for the chosen experimental approach
and/or for the different timeline of similar experiments from the competitors. These aspects have to be
kept in mind in the specific construction planning of the Hadron Hall extension.
The activity in the recent past at J-PARC in the area of nuclear and hadron physics is marked by excellent
results that were possible thanks to the intensity and quality of the secondary beams. These results
constitute a very solid basis and give strong motivation to new and more challenging investigations to
explore new directions as that of multi strangeness, of the hot compress matter and to reach higher
sensitivity for the search of flavor changing rare processes. Improved experimental conditions and morebeam time are needed for the next achievements.
After being included in the KEK-PIP in 2016 as project that needs new funding, the Hadron Hall
extension project has progressed in producing detailed construction planning to optimize the beam
conditions for the physics goals and in defining the different phases for the project implementation. The
redefinition of the project in order to realize it in phases has been very positive taking into account thepresent budgetary condition. Within this framework the clarification of the near-term schedule andpriority, including the MR power upgrade, a new HD target, the high-p beam line and COMET phase 1,
has been an important step for laying down the longer-term planning.
At the present conditions, the SAC endorses the proposal to start first with the realization of the highintensity high resolution pion beam project. This will allow, thanks to its uniquely high energy resolutionof the beam, performing super precision spectroscopy of hypernuclei and will assure the lead of Japan in
the study of strangeness in nuclei for aspects related to nuclear structure and interactions. The
collaboration with RCNP and RIKEN should also be reinforced further in the next years and a constantdialog with the theory groups addressing this physics should also be undertaken.
For the other components of Hadron Hall extension beyond the phase 1, all of them are recognized tohave high scientific validity, and the necessary R&D and the design towards the possible accommodation(in particular KOTO 2) in the first phase should be investigated.
4.3 Future light source
It is clear that there is a very loyal user base and managing them through focused workshops, surveys etc.
would be helpful. Extensive consultation with the user community is critical to any future strategy. What
do they want in the short, medium and long term? This would form the basis of a “science case” fromwhich a technical case around machine considerations would naturally evolve.

7

Where will new users come from and what will they expect from a light source? It is clear that newscience at light sources may not always require the brightest and most coherent sources. Rather, as was
highlighted in the presentations, there is room for a range of facilities. The PF is well placed to make thisevaluation and, based on it, deliver what is needed. It needs to prioritize its areas to develop.
The industry program represents more than an income stream. It is a tool for engaging new users andenhances community outreach. It also highlights to funders a return on investment that is tangible to thecommunity. With this in mind the PF should review its partnership program and extend it to other areas ofscience. From a purely financial perspective this will offset the reliance of additional income from its
crystallography service business.
Multi beamline access at light source facilities is increasing worldwide as a result of demands ofmultidisciplinary large-scale scientific projects. The PF represents a comparatively large user base within
KEK and as such multi beamline access could take on a unique dimension. The KEK quantum beam
platform represents an exceptional worldwide opportunity. Synergies between the photon and neutron
beam user base might be a good starting point and novice users should be encouraged through a targetededucation program and elements of a linked proposal system.
5. Topics at the next SAC meeting
The SAC encourages the KEK team to further develop the strategy for future light source facilities at
KEK. The SAC looks forward to a presentation on this development at the next SAC meeting.
The SAC would also like to hear about KEK’s current and future leadership roles in materials science andstructural biology.
The budgetary condition has been a continuous challenge and it has impacted the available operation timeof the accelerator facilities. The SAC looks forward to a presentation on KEK’s prioritization-making anddecision-making process and on a coherent plan at J-PARC at the next SAC meeting. A graph showing
ongoing and future project/program profiles (budget and human resources) over the next decade will be
helpful for the SAC to understand the overall picture of current activities and future plans.
In addition, the SAC would like to hear about the staffing plan for accelerator experts at the next SAC
meeting.
