Bridging users and RNC• Charter (https://ribfuser.riken.jp/RIBF_UG/charter.html)• The purposes of the RIBF-UG are as follows:– To provide a formal channel for the exchange of information between the RIBF
administration and the scientists who utilize this facility for research.
– To provide advice and feedback to the RNC Director on matters relating to thedevelopment and operation of the RIBF.
– To promote and enhance the effective use of the RIBF by collecting users concerns.
– To act as a supporting and consulting body for the RIBF. The RIBF-UG maintains
communications through appropriate means, such as regular meetings, electronic mailinglists, shared data bases, and webpages.

• UEC: coordinate the activities of the RIBF-UG (Charter 3)• UEC starts to survey/collect concerns and requests of users using Google form

Web Meeting, 04 March, 2022

• COVID-19• RIBF operation in 2nd half FY2021• MT plan in 1st half FY2022• NP-PAC meetings

COVID-19 … current status• In Japan/Tokyo area
– Still under “quasi-state of emergency”– At least until March 21• Still difficult for foreigners to visit RIKEN for experiments– On March 1 regulation changed:
Entry foreigners 3,500/day5,000/day (~400,000 waiting)
RIKEN… focusing on new employers (~30 in March, ~90 later)
RIKEN’s priority list  MEXT  MOFA

• In RIKEN– Keep “Level-1” regulation• Research activities OK but with best care
• Accelerator use … < 20 participants/experiment• Guideline and checklist for visitors

Breakdown of BigRIPS large cryocooler compressor motor
December 3 around 7:30am
Bearing on the compressor side of motor got damaged, and heated.
Bearing grease evaporated, big amount of smoke emitted.

bearing In January the maker company fixed it in their factory by renewing bearing.
There was no problem in the other parts, motor coil and so on.

Nuclear Many-body Theory Laboratory(核⼦多体論研究室)
Masaaki Kimura (RIKEN/Nishina)

A new Lab. for nuclear theory○ Nuclear Many-body Theory Laboratory (核⼦多体論研究室) has been launched(Group director: Masaaki Kimura)○ The laboratory will be in full-function from April○ In FY2022, Kimura will work both at RIKEN and Hokkaido Univ.
He will work full-time at RIKEN from FY2023
Lab room is at 4th floor of RIBF blgd.

As of Mar. 1st, the laboratory room is under renovation

Goals of the Lab.
Primary Goal: Promotion of theoretical studies for nuclear structure and reactions.
Our priority is “physics of unstable nuclei”〇 Theoretical studies of unstable nuclei
in collaboration with RIBF experiments- Exotic nuclear structure and reactions
at the limits of nuclear existence- Nuclear reactions at explosive phenomenain the Universe, and the origin of elements

Theory〇 The Lab. will be a platform for thecollaborations between RIKEN anddomestic/international theory groups
A workshop for unstable nuclear physics
will be organized at RIKEN
on May 30-Jun.1 (TBA)

RIBF

Goals of the Lab.
Secondary Goal: Nuclear physics for applications
Research and Development of nuclear database for applications

Fundamental research
Nuclear decommissioning

Medical Isotope production
Cancer therapy〇 We are working for the R&D of nuclear reaction databaseusing nuclear reaction model + AI
⇨ this will enhance the productivity of RIBF
Coupled Channel Optical modelAI+Research opportunities
For the Lab. activities, the contributions from young generations are essential.
We can offer a nice postdoc experience at RIBF
For Postdocs〇 A postdoc position founded by JSPS budget (Application will open in Apr. or May.)〇 Special Postdoctoral Researchers at RIKEN (Deadline is Apr. 14th)〇 JSPS Postdoc fellowship (Applications open in May.)For Ph. D students〇 Junior Research Associate (JRA) for students in Japanese University.
(Applications opens in Sep.)〇 International Program Associate (IPA) for overseas students(Applications opens in Apr. and Oct.)

We expect many applications from young people.
