A Study of Beam-wave Interaction Parameters on an X-band Sheet Beam Klystron

摘要

The sheet beam klystron is a new kind of microwave vacuum device, which uses a high aspect ratio, thin rectangular beam to reduce space charge effects, increase power capability and beam-wave interaction efficiency. In this paper, two main beam-wave interaction parameters: coupling coefficient and beam-loading were studied, the theoretical formula and a 3D PIC simulation code were used to compute them respectively, and the results of two methods were compared.
