TL;DR: The implementation of top-up operation at SPring-8 is described, with a focus on the simultaneous achievement of stability of stored current, beam orbit, purity of an isolated single bunch, and beam injection efficiency.
Low-power rf systems for the kekb injector linac
TL;DR: In this article, the low-power rf systems of the KEK electron linac have been upgraded for the KEKB ring, and the main drive system is equipped with a new frequency multiplier/divider which generates five reference signals for the linac.
Proceedings ArticleDOI
Linac upgrade plan for the KEK B-Factory
TL;DR: In this article, the acceleration energy of the linac must be upgraded from 2.5 to 8 GeV, and the most effective way has been searched from several points of view, such as the beam quality, ease of beam handling, and construction.
