Abstract

A feasibility study of the stability of a superconducting crab cavity for a B Factory was carried out. The study was done for the two trapped modes: the longitudinal TM010 and transverse TE111. It was found that for both modes the voltage induced by the beam bunches will be less than +or-20 kV for the TM010 mode and +or-1 kV for the TE111. Using the ZAP code it is shown that a stable frequency regime for the TM010 mode can be found in which the worse growth time is eight times larger than the radiation damping time. For the TE111 mode the high energy ring is stable while the low energy ring will have to be stabilized by the feedback system.<>
