CSR电子冷却系统强流电子束包络的振荡特性
Study on the envelope oscillation of intense electron beam in CSR e-cooler system
摘要
HIRFL-CSR的电子冷却系统是采用强流电子束对重离子束进行冷却.在冷却段漂移管区,由于强流电子束自身的空间电荷场和螺线管磁场的作用,使得电子束的包络发生振荡.通过求解电子束的横向包络方程,研究了强流电子束包络随电子束参数和螺线管聚焦磁场的变化关系.计算结果表明:对于不同的电子束能量和磁场,电子束包络的振荡频率也不相同;在相同的条件下,磁场越强,电子束包络振荡幅度越小,电子束能量越大,其包络的振荡频率也越快.
Abstract
An intense electron beam is adopted in HIRFL-CSR e-cooler system to cool down heavy ion beams. In the driftspace of the cooling section.The envelope of electron beam oscillates due to space charge field and solenoidal field. By solving the transversal envelope equation，the envelope oscillation of intense electron beam is preliminarily studied.The caculation results show that in the same case.the stronger the magnetic field is,the smaller the envelope oscillation is;meanwhile the larger thebeam energy is the larger the oscillation frequency is.
