Abstract

A strong excitation of the longitudinal coupled-bunch instabilities, which is suspected to be driven by the TM/sub 011/-like mode of the DORIS-I cavities, was observed at the higher electron beam current in the storage ring of SRRC. Such instability leads to heavy fluctuations of the photon beam intensity in the horizontal plane and therefore restricted the maximal useful beam current for the user experiments. This restriction has been released by replacing the damping antennae with the additional tuners. Here, we report our experiences after one-year routine operations of the main RF cavities with the second tuners at SRRC.

用高阶模频率调谐器稳定谱强度波动

在SRRC的存储环中，在较高的电子束电流下，观察到纵向耦合束不稳定性的强烈激发，怀疑是由doris - 1腔的TM/sub - 011/ like模式驱动的。这种不稳定性导致光子束强度在水平面上的剧烈波动，从而限制了用户实验的最大有用光束电流。这一限制已被释放与额外的调谐器取代阻尼天线。在这里，我们报告了我们在SRRC使用第二调谐器对主射频腔进行为期一年的常规操作后的经验。
