Comparative EGUN and TRAK simulation studies on the design of the magnetron injection gun of a 200kW, 42GHz gyrotron

Abstract. A triode-type magnetron injection gun (MIG) for a 42 GHz, 200 kW gyrotron was designed by two commercial codes: EGUN and TRAK. An in-house code MIGANS was used as the post-processor of the EGUN. Some basic equations relevant to the problem available in literature were used while using the EGUN code for the purpose. The results on the design output parameters obtained by these two codes were found to be in close agreement

High voltage analysis of electron gun for low power and high power gyrotron

728-735<span style="mso-bidi-font-style: italic" lang="EN-GB">The paper presents the high voltage analysis of Magnetron Injection Gun for 42 GHz, 200 kW and 120 GHz 1 MW gyrotrons. The Finite Element Analysis code TRAK has been used for the analysis of high voltage breakdown. In the analysis, the potential and electric field are estimated only at the critical regions between two electrodes, where the chance of voltage breakdown is prominent. </span

Development of Cooling System for Gyrotron Collector

In this paper, the development of cooling system for 42 GHz, 200 kW gyrotron collector is presented. The design of the cooling duct has been finalized after different analyses such as, the fluid analysis, the thermal analysis, the structural analysis, etc. All analyses have been carried out by ANSYS software and the development of the cooling system based on the final design is performed
