Description
Bunch lengthening technique is most reliable method to mitigate the intrabeam scattering in synchrotron light sources. The performance of the bunch lengthening can be degraded by a transient beam-loading (TBL) effect, which becomes large when long gaps are introduced in the bunch filling pattern. To mitigate the TBL effect, we have proposed a compensation method using a broadband cavity [1]. We have investigated the conceptual design of the kicker cavity and carried out the performance tests of the low-power model cavity that can be used to compensate for the TBL effect [2]. In this presentation, details and further discussions about the performance of the TBL compensation will be reported based on the results of the performance tests and semianalytical calculation. As an example, the TBL compensation at the KEK PF 2.5 GeV ring is investigated using semianalytical calculations. The strategy of the TBL compensation at the PF ring is discussed. The performance of the TBL compensation using the kicker cavity is investigated.
