合肥光源束流能量标定装置

Set-up for electron beam energy calibration in HLS

为在合肥光源储存环上利用共振退极化的方法建立一套测量电子能量的装置,计算了储存环电子束流建立极化的时间、退极化场的分布、激发条带的功率以及退极化时间,并且利用束损系统测量了由于耦合度和腔压变化造成的束流托歇克的变化,以期用现有的束损系统监测退极化造成的束流托歇克的变化.

To build the set-up for energy calibration of electron beam by the method of resonant depolarization in HLS, the polarization time of the electron beam of Hefei storage ring, the distribution of depolarization field and the input power of exiting trip and depolarization time were calculated. With the beam loss monitor system, the relative change in the beam lifetime arising from increase in the coupling degree and cavity voltage was measured, so as to measure the change of Touschek lifetime to depolarization.
