| Abstract |
Large dynamic vacuum pressure rises of orders of magnitude which caused by the lost heavy ions can seriously limit the ion intensity and beam lifetime of the intermediate charge state heavy ion accelerator. The High Intensity heavy ion Accelerator Facility (HIAF) which will be built by the IMP will accumulate the intermediate charge state ion 238U³⁵⁺ to intensity 3×10¹⁰ ppp to different terminals for nuclear physics, nuclear astrophysics and so on. In order to control the dynamic vacuum effects induced by the lose beams and design the collimation system for the BRing of the HIAF, a newly developed dynamic vacuum simulation program is conducted to optimize the collimation efficiency. Furthermore, two dedicated desorption measurement setups have been established at the terminal of the CSRm and 320 kV HV platform to study the molecular desorption process and do the benchmarking of the simulation code. This presentation will describe the collimation efficiency optimization, measurement results with Sn beam at the CSRm and withthe Xe beam in the HV platform.
