Abstract

1407_54It is shown that cross-coupling among cavities may reduce beam breakup (BBU) growth in a recirculating accelerator. The main reason for this growth reduction is the sharing of the deflecting mode energy among coupled cavities. This result is based on a numerical study of the proof-of-principle experiment currently planned for the spiral line induction accelerator (SLIA, 35 ns, 10 kA, 8.5 MeV). Reduction of BBU amplitude by factors of several hundreds is also predicted for a SLIA upgrade (35 ns, 10 kA, 25 MeV) which consists of a 7-turn, 70-cavity system. Various issues are addressed.
