储存环内纵向Palmer方式随机冷却过程模拟

Simulation of Stochastic Momentum Cooling Process With Palmer Method in a Storage Ring

基于Fokker－Planck方程，模拟了兰州重离子加速器冷却储存环（HIRFL-CSR）实验环内重离子束的Palmer方式纵向动量冷却过程，在模拟过程中，得到并应用使冷却达到最快的系统最优增益曲线．对模拟结果进行了讨论．

For the Proposed Lanzhou Heavy ion Cooler Storage mug (HIRFL-CSR),stochastic cooling is studied tO improve the beam quality and increase the luminosity. The longitodinal stochastic cooling Process of a stored beam with Palmer method is simulated,based on the Fokker-Planck equation. OPtimum gain is obtained and applied during the simulation with the designed hardware Parameters. The resultS are discussed. Received 17 March 1998
