 Objectives:
1.The objective of ANPhA is to strengthen ”Collaboration” among Asian
nuclear research scientists through the promotion of nuclear physics and its
transdisciplinary use and applications.
2.The objective of ANPhA is also to promote “Education” in Asian nuclear
science through mutual exchange and coordination.
3.It also aims at “Coordination” among Asian nuclear scientists by actively
utilizing existing research facilities.
4.Furthermore, at a later stage, it will help to discuss future planning of
nuclear science facilities and instrumentation in Asia.

11. RIKEN RIBF in Coming 5 Years
SHE: Start an experiment to hunt Z>119 (GARIS/GARIS2)
RIBF Accelerator / Facility
Proton to Uranium, with Electrons+photons,
We aim to have 345MeV/A U beam reaching 100pnA ( 20 times to go)
days user beam time par year (Budgetary challenge after Fukushima problem)
Experiments
Will measure the major characteristics of ~100 key unstable nuclei close to R-process path.
Will contribute to establish the ultimate picture of nucleus
To achieve above
BigRIPS/ Zero-Degree/ EURICA/ SAMRAI/ SHARAQ - Active
SCRIT will be operational in a year
The rare RI Ring is under construction; the first data in three years
Return Beam Line for polarized unstable beam will be ready in three years
Slow RI Facility within three years (hopefully)
Organization
We wish to invite more international participations
Will establish RIBF consortium (exp and theory)
Please consider to have your branch at RIKEN Nishina Center
Future Project
Re-acceleration of RI (ISOL or Fragmentation with SLOW-RI)
Hope to reach The Island of Stability 11

13. CRIB Primary beam from K=70 AVF cyclotron.
・　 CNS Radio-Isotope Beam separator , operated by CNS (Univ. of Tokyo), located at RIBF (RIKEN Nishina Center).
Low-energy(<10MeV/u) RI beams by in-flight method.
Primary beam from K=70 AVF cyclotron.
Momentum (Magnetic rigidity) separation by “double achromatic” system, and velocity separation by a Wien filter.
Orbit radius: 90 cm, solid angle: 5.6 msr, momentum resolution: 1/850.
This figure shows the CRIB spectrometer which is located at RIBF facility of RIKEN Nishina center.
CRIB is operated by CNS, the University of Tokyo.
The CRIB consists of two magnetic dipoles and a Wien filter.
The primary beam from the AVF cyclotron is focused onto the production target.
The produced secondary particles are separated by magnetic dipoles and Wien Filter.
The F1 focal plane is a dispersive focal plane. We can select the secondary beam by momentum of it.
The F2 focal plane is a double achromatic focal plane.
The Wien filter is attached to the downstream side of F2 to provide additional background suppression of undesired isotopes.
Next, I’ll explain the detail of production target and the Wien filter. 13

36. Some perspectives
We are working for the future of NS and the next generations of nuclear scientists, and therefore long term scope is extremely important.
Coordinated personnel exchange would be of major importance which benefit both sides, including PhD students （already many）, post-docs, fellows and visitors. We should make all effort to implement these exchanges. There comes possibilities in China, and we need to get help from FRIB side to apply and setup the specific plans. (How to coordinate?)

37. Attract more young talents to the science ( NP in particular) fields is very important. China may be a large pool of science students, as in the past. Internationally coordinated effort would be very useful (Ex.: Nishina School) . Could Theory Alliance + CUSTIPEN + Talent program find a combined way to do something (School、Teaching？).
It is also important to identify some mutually interested detector + physics subjects:
Modest scale: pieces of detector; beam test;
data analysis, etc.
Mid- & Large scale: real part of detector system + Physics program, more difficult…
(Exploration by WGs).

39. Converting subjects into projects, competing for funding
Converting subjects into projects, competing for funding. There are many possibilities.
(past example, future model, …
need good coordination and mutual effort)
Further successful ! Benefit to both sides !
