【Abstract】 The preliminary design of a multi-beam klystron gun of Beijing Vacuum Electronics Research Institute is presented briefly in this paper.A kind of way is adopted in this klystron by using fast warming up cathode.The electron gun structure,steady state and transient thermal analysis are designed and optimized,respectively.It shows that the warming up time is less than 150 seconds in cathode fast test experiment,which achieves the program objective.更多还原
