Abstract

Optimizing coupled-cavity traveling-wave tube (CCTWT) beam wave interaction (BWI) efficiency through tapering of the phase velocity could greatly increase RF output power. In order to do this work, a programme for CCTWT has been developed and implemented in BVERI. The programme could do multidimensional large-signal calculation of CCTWT and optimize the lengths of the individual cavities using simulated annealing algorithm. The optimization algorithm is described simply and computational results are present.
