【摘要】 随着CSR的建成和兰州重粒子加速系统(HIRFL)实现质子加速,HIRFL现有的束流传输系统已不能满足越来越多的物理实验对供束时间的要求,为此,对原有的HIRFL的束流输运系统进行了分时供束改造,新的束流分配系统可以在给CSR供束和不供束两种情况下,同时使用SFC和SSC的束流在多个实验终端进行物理实验,介绍了新设计的HIRFL束流分配系统的布局和束流光学计算结果。更多还原

【Abstract】 With construction of CSR and acceleration of proton at HIRFL, the existing beam handling system can not meet the requirements of nuclear physics experiments for more and more beam time. For this reason, a new beam distribution system based on time is being constructed. The new system not only deliuers beams to the new terminals for reaser-ch program of proton and heavy ion therapies, single particle effects of spaceflight electronics components and irradiration effecs of living things, but also can provide beams for CSR when physics experiments are done on the experimental terminals with the beam from both SFC and SSC. The layout, performance and beam optics calculations of the new distribution system are presented.更多还原
