理研の加速器小史と RIBF 建設の回想―日本の加速器科学発祥の地「理研」 創立 100 周年に寄せて―

抄録

This year is the 100^th anniversary of the RIKEN, the original campus of which was located at Komagome, Bunkyo-ward in Tokyo. There Dr. Yoshio Nishina “the father of Japanese modern physics” initiated “Japanese accelerator-based science” in 1930’s and led to the world top level. But after the defeat, its level had been behind America and Europe. Through the long-time struggles, Japan successfully has caught up them, and now is again on the top level. In this article, I describe briefly a history of RIKEN’s ion accelerators, and looked back over the construction of the RI Beam Factory (RIBF) unparalleled in RI beam production capability, which we proposed and led.
