Abstract
In order to meet the high requirement of beam intensity in a short time, a new injection method named two-plane multiturn injection is proposed for HIAF/BRing. This method is different from the traditional single-plane multiturn injection, and it has no practical operation experience. This will be the first time to be used in a practical project. Therefore, it is necessary to verify the feasibility of the two-plane multiturn injection scheme through program simulation. In order to simulate and study the injection process in detail, and to overcome the disadvantages of existing programs such as slow tracking speed and inconvenient modification of injection parameters, the injection model and TPIS (Two-Plane multiturn Injection Simulation) program are developed. By comparing with the simulation results of ORBIT program, it proves that the TPIS program is correct to simulate the two-plane multiturn injection process. On this basis, particle swarm optimization algorithm is added into the TPIS program, and the injection parameters are optimized. The results show that the TIPS program can be used for injection parameter optimization. After the optimization, the injection beam loss is reduced by 28%, and the final accumulate particle number can meet the requirement of design beam intensity. It also verifies the feasibility of two-plane multiturn injection.
