私の加速器遍歴（Ⅲ）幻のニューマトロン計画が拓いた原子核科学の地平

抄録

My wandering about accelerator extended more actively to challenge new fields of physics with use of the high-energy heavy-ion beams. With people in the Japanese nuclear-physics community, we proposed to build a new high-energy heavy-ion synchrotron, named NUMATRON, which accelerates nuclear beam up to a few GeV per nucleon. Since it was brand-new field of nuclear physics, when proposed, we started to join a program at the LBL Bevatron/ BEVALAC to learn and to get experience in the new field. Although the NUMATRON proposal was not realized while the competing TRISTAN proposal was accepted, the experience and the effort for NUMATRON opened the new horizon of nuclear science in various directions.
