A new approach for Next-TRIAC

COFFEE_KLATCH · Invited

Abstract

TRIAC (Tokai Radioactive Ion Accelerator Complex) is a unique RIB facility in Japan based on the ISOL and post-acceleration scheme. It has been operated as a User Facility since the November of 2005. Fission fragment beams via the proton-induced uranium fissions of 10$^{11}$ fis/sec are available in the acceleration energy range 0 to 1.1 MeV/u. At this moment, before considering an immediate extension (or upgrade) of the present TRIAC in terms of facility, we have proposed a new research program, which is supposed to be one of important physics programs at the next generation of TRIAC-like facility (Next-TRIAC). That is an experimental approach to study unknown nuclei in the vicinity of waiting region for A=195 r-process abundance peak through the multi-nucleon transfer reactions of neutron-rich beams. In the talk, after the brief summary of TRIAC activities, I will introduce an outline of our short term experimental proposal and underlined physics motivation relevant to the future's Next-TRIAC. Also I will mention some important R{\&}D subjects to be solved in the short term project.
