Numerical simulation on beam breakup unstability of linear induction accelerator

A code is written to simulate BBU in induction linac according to theoretic analysis. The general form of evolution of BBU in induction linac is investigated at first, then the effect of related parameters on BBU is analyzed, for example, the alignment error, oscillation frequency of beam centroid, beam pulse shape and acceleration gradient. At last measures are put forward to damp beam breakup unstability.
