摘要：
In this paper, the simulation of ion noise in periodic permanent magnetic field traveling wave tubes is conducted. Through calculation, it is found that the residual gas in the traveling wave tubes is ionized, and the diagnostic of the ion number shows an obvious period which corresponds to the fluctuation of the average kinetic energy.
