OBSERVATION OF TRANSVERSE COUPLED BUNCH INSTABILITY AT KEKB

摘要

Transverse coupled bunch instability was experimentally studied in low energy positron ring (LER) and high energy electron ring (HER) at KEKB. The oscillations of bunches were recorded by a bunch oscillation recorder for the total of 4096 turns. The data were analysed to obtain the mode distribution and the growth rate of oscillation. The result of the analysis is presented in this paper.
