Design and Analysis of Electron Gun and Collector Test Module for 250kW CW, 5GHz Klystron

The present paper deals with the designing and simulation of electron gun, collector and electromagnet for 250kW CW, 5GHz klystron. The assembled structure named as Gun collector test module (GCTM) is also designed to validate the gun perveance and thermal design of collector. The electron beam optics is designed in TRAK 1D code and MAGIC2D code. Based on the above simulation, the engineering drawing is prepared and piece parts development of electron gun has been done successfully. The integration of collector and electron gun is designed using TRAK and validation of the design is done in MAGIC2D code. The results are well matched with the theoretical predictions. Using the simulated data, the engineering design of collector has been made and the fabrication of plain collector has been carried out successfully. The electromagnet is simulated using TRAK software to focus the beam properly The design analysis of complete Gun Collector Test Module is to be discussed in this paper.
