Beam instability due to higher-order modes of APS cavities in the Tristan accumulation ring
- 1. National Lab. for High Energy Physics, Tsukuba, Ibaraki (Japan)
Description
Shifts of resonant frequencies of the APS cavity were measured as a function of the tuner position and cavity temperature. From this measurement we found that cavity temperature warm-up plays an important part concerning coherent instability. There was evidence that the accumulation current was limited by resonance with higher-order modes. We could identify which cavity mode was responsible for the transverse coherent instability. (orig.)
