兰州重离子加速器冷却储存环射频堆积过程模拟

Simulation of RF Stacking Process in HIRFL-CSR

考虑了重离子冷却储存环中粒子纵向相振荡的运动特性及电子冷却的作用 ,模拟兰州重离子加速器冷却储存环 (HIRFL CSR)主环中的射频堆积过程 ,给出了高频参数在射频堆积过程中随时间的变化曲线 。

The beam RF stacking process for heavy ion beam, such as 12C6+ and 40Ar18+, in HIRFL-CSR main ring(CSRm) is simulated by taking the beam longitudinal phase oscillation and electron cooling into account. The phase movement equations are solved by 4-order Runge Kutta methods. The main RF parameters against time are obtained. It provides the theoretical basis of the RF cavity design and the parameters pre-set for operation of the machine.
