ARIS2014 - 2nd Conference on Advances in Radioactive Isotope
ScienceT. Motobayashi∗1The second conference on Advances in RadioactiveIsotope Science (ARIS 2014) was held at the Ito International Research Center in Tokyo on June 1-6,
2014. It was jointly organized by the RIKEN Nishina
Center and CNS, the University of Tokyo, sponsoredby IUPAP (International Union of Pure and Applied
Physcs), and supported by several Japanese institutions and societies. The first ARIS conference washeld in 2011 in Leuven, Belgium, by merging the twomeetings, ENAM (International Conference on Exotic
Nuclei and Atomic Masses) and RNB (InternationalConference on Radioactive Nuclear Beam). In a joint
assembly of the advisory committees of the two meetings, the ultimate goal of ARIS was set to create the“flagship conference” series on the science of radioactive isotopes, including the physics of exotic nuclei andstudies with RI beams. Since the Nishina Center andthe CNS have extensively studied on radioactive isotopes with excellent RI-beam facilities and their significant contributions in the near futre are foreseen, thesecond conference in Japan was very well-timed.
The scientific scope of ARIS 2014 was of the following subjects, taking over the ones of the first conference with some modifications: 1)nuclear structure,2)nuclear astrophysics, 3)fundamental symmetries andinteractions, 4)nuclear reactions and responses, 5)nuclear properties including atomic masses and fundamental constants, nuclear moments and radii, rare decay modes, and nuclei at the driplines, 6)nuclear EOS
and its implications, 7)heaviest elements and fission,8)radioactive isotope production and developments ofexperimental devices, 9)computational developments,
10)applications, and 11)other related issues.
On Sunday June 1, public lectures attracted a large

audience of about 300 people including high school students. The conference started on Monday with the welcome address by the Conference Chair, Hideto En’yo.
In the first scientific session chaired by the Conference
Co-chair, Takaharu Otsuka, Robert Janssens gave thekeynote talk addressing “big” questions in the field andproviding an overview of the new and important developments after the first conference.
The number of registrants turned out to be 407 from27 countries. Thus the higly optimistic goal set by theorganizers was reached, reflecting the considerble interest and amount of work done in this the research
field. The conference photo shown below (Fig. 1) delivers the lively atmosphere of the conference.
There were 48 plenary talks and 82 oral presentations in three parallel sessions held on June 3 and 6 afternoons. Recent highlights from RIBF, the new neutron magic number 34 experimentally confirmed forthe neutron-rich nucleus 54 Ca and first life-time measurements for a number of nuclei in the r-process path,for example, attracted much attention as well as newresults from world facilities. Among 239 papers presented in poster sessions, seven posters presented byyoung scientists were selected as “Best Posters”, andthe awarding ceremony took place in the closing session. Angela Bracco summarized the conference byselecting major aspects from numerous presentations
and emphasizing the bright future of the field.
The conference proceedings will be published electronically in the JPS Conference Proceedings Volume
6 (2015). The next ARIS conference will be jointly
hosted by NSCL and TRIUMF.

The 8th Nishina SchoolT. Kishida∗1 and H. Ueno∗1The RIKEN Nishina Center (RNC) has commenced
Nishina School to enhance international research relationship in the Asian Region through human-resource
development in the ﬁeld of nuclear physics. In this program, undergraduate students are being accepted bythe RNC from Peking University since 2008 and fromSeoul National University since 2012 for two weeks every summer. Both the programs have been mergedsince 2013.
The 8th Nishina School was held from July 28 toAugust 8, 2014. The curriculum of the School was designed to introduce the pleasure of nuclear physics into
the undergraduate students from Peking University (5students) and Seoul National University (5 students).
The ﬁrst week, program consisted of lectures and basic experimental trainings. In the second week they
performed a real-beam experiment using the RIKEN
Pelletron accelerator, starting from its planning andfollowed by the analyses and the discussions. On thelast day of the School, the presentation session by thestudents was held. The program timetable in 2014 isshown in Fig. 1.
In response to a request for improving the management of the Nishina School proposed by the people incharge of the Nishina School held in the last year, theRNC director convened a preparatory meeting on December 25, 2013, to discuss the development of an organizational management system of the Nishina School
and the improvement of transparency in the decisionmaking process. For this purpose, it was determined atthe meeting to newly set up the Nishina School Steering Committee. The Committee is composed of Ueno(Chair), En’yo, Sakurai, and Sakai. The Committee
Meetings were held four times on March 3, April 23,May 26, and July 15, 2014. Kishida, principle of theNishina School, also attended all these Meetings as anobserver. Their meeting minutes were reported at thesecond, fourth, and ﬁfth RNC Coordination Committee Meetings held in 2014.
In order to enhance the experimental training, theCommittee determined to incorporate accelerator experimental training into the curriculum. In this year,
cross-section measurements were conducted for the12C(p,γ)13 N reaction utilizing a proton beam at Ep =1600–1850 keV delivered from the RIKEN Pelletronaccelerator. Technical instructions of the experimental training were provided by Research Scientists inNuclear Spectroscopy Lab., Spin Isospin Lab., and RI
Physics Lab. They were technically assisted by IPA
and JRA researchers of these laboratories.
The Committee also considered that enhancement∗1of working-level dialogue among the persons in chargeof, e.g., the entire program, experimental trainings,
and oﬃce procedures is an important subject. Thisyear, three working-level meetings, including an onsite meeting at the Pelletron, were held on July 4, 10,
and 18. Despite such a gradual improvement, the situation can be further improved.
All the students had a good experience and enjoyed
the School and life at the RNC. Figure 2 shows a photograph taken at the opening ceremony on July 28.

Development Society (INTDS2014)
H. Okuno,＊1 H. Hasebe,＊1 H. Kuboki,＊1 H. Imao,＊1 A. Yoshida,＊1K. Morimoto,＊1 D. Kaji,＊1 K. Yoshida,＊1 and K. Sakuma＊1
The 27th World Conference o f the International Nuclear
Target Develop ment Society (INTDS 2014) was held fro mAugust 31th to September 5th, 2014 at the National
Museum of Emerging Science and Innovation (Miraikan) inOdaiba Tokyo, Japan with special emphasis on targets foraccelerator-based research. INTDS 2012 was organized by
the RIKEN Nishina Center for Accelerator-based Science,Saitama.
The series of INTDS conferences dates back to 1963
when the "First Symposiu m on Research Materials for
Nuclear Measurements" was held sponsored by the Central
Bureau for Nuclear Measurements (CBNM; recently,IRMM ‚ -Institute for Reference Materials andMeasurements) in Belgiu m. Since then, researchers
involved in target preparation shared their experience anddiscussed related problems during biennial conferences
hosted alternatively in Europe, North A merica, and Asia
(www.intds.org). The 23rd INTDS conference was held inTsukuba, Japan in 2006. It was delightful to meet again inJapan on the occasion of the 27th International INTDS
conference.

More than 77 participating scientists fro m 17 countries(Belgiu m, Canada, China, France, Germany, India, Italy,Japan, Korea, Pakistan, Poland, Ro mania, Russia, SouthAfrica, Swit zerland, UK, USA), met in Tokyo to present
over 67 scientific contributions covering the wide field of"State-of-the-art Technologies for Nuclear Target andCharge Stripper". A laboratory tour of the RIKEN RI Beam
Factory was included in the scientific program to introduce
the institution and laboratories. The conference comprised
eleven different sessions titled ‚"Targets and strippers for
RIBF", "Classical accelerator targets", "RI beams", "Gasstrippers", "Liquid strippers"‚ "Production targets"‚"Medical and industrial applications", "Radioactive targets","Target characterization", "Liquid and gas targets","Radioactive targets", and "Laser-related targets". The
sessions included many activ ities such as the discussion ofexcit ing new developments or methods, reports on
improvements of established techniques, presentation ofscientific results by young scientists, and the introduction ofnew groups and laboratories in the society.

The 6th International Conference on Trapped Charged Particles andFundamental Physics
M. Wada,*1 P. Schury,*1 Y. Ichikawa,*1 and Y. Ito*1
The 6th International Conference on Trapped ChargedParticles and Fundamental Physics (TCP2014) was heldfrom 1st to 5th December, 2014 at the Takamatsu
International Conference Hall. Prior to the conference, apreschool (TCP school) for young researchers wasorganized from 28th to 29th November at the Nishina Hall ofRIKEN where inspiring lectures were given by S. Ulmer, R.
Thompson, R. Hayano, H. Katori, V. Dzuba, Yu. Litvinov,
W. Nörtershäuser. About 60 participants enrolled in theschool and half of them went to Takamatsu.
During the conference, a variety of scientific programs
using stored particles were actively discussed.
Anti-Hydrogens are routinely synthesized and precision
spectroscopy of them is being actively pursued.
Multi-reflection
time-of-flight(MRTOF)
mass
spectrographs were put online at three different laboratories
at almost the same time at ISOLDE, RIKEN and GSI, andare also under preparation at TRIUMF, MSU, ANL, and
IBS in Korea. Advanced resonance detection methods inPenning trap mass spectrometers were discussed. Several
fundamental symmetry studies using molecular ions, neutral
atoms and highly charged ions (HCI) were discussed. The
highlight of the conference was a sympathetically cooled
HCI crystal in a linear Paul trap by Heidelberg-Aarhus
collaboration. It can be a next-generation frequency
standard, but also provides a platform for research inphysics beyond the standard model such as time variation of
the fine structure constant. An Australian theorist suggeststhat Cf16+ is the best candidate for such research at present.

A total of 107 registered participants attended and 63% ofthem were from abroad. We invited 47 speakers. Of them,
45 accepted the invitation, 2 of whom later cancelled. We
accepted 23 oral presentations and 26 posters; additionally,
3 oral contributions included posters.
An international workshop, NNP2014, was held at thesame time and location, hence joint sessions and social
events were held.
In the international organization committee meeting, it
was decided that TCP2018 will be held in USA andorganized by G. Bollen of MSU.
