For reliable operation of high power microwave sources such as high power gyrotron demands stringent vacuum conditions to be fulfilled. In this paper, the vacuum requirements of a 42 GHz, 200 kW CW/ long-pulse gyrotron has been presented and also includes requirement for its heat treatment and vacuum processing.
A open resonator for a 42GHz, 200kW gyrotron for an Indian TOKAMAK system has been designed. The RF characterization of open ended tapered cylindrical resonator for a gyrotron is considered to see the performance of the resonator before the final assembly of the device. The experimental results for cold testing of first Indian gyrotron open resonator are present in this paper. The experiments were...
The design of 42 GHz, 200 kW Gyrotron has been carried out using in-house and commercially available software's. A triode type MIG has been designed using EGUN code and three in house developed codes MIGSYN, GINTMESH and MIGANS respectively. A weakly tapered interaction cavity has been designed to excite TE03 operation mode. A software GCAVSYN has been developed to synthesize the cavity geometry and...
This paper presents a three-dimensional (3-D) simulation of a triode-type magnetron injection gun (MIG) for a 42-GHz 200-kW gyrotron with a transverse-to-axial velocity ratio of the electron beam at 1.22 and a maximum transverse-velocity spread of 3.2%. The operating mode of the gyrotron is TE_03, and it is operated in the fundamental harmonic. The MIG has been designed by using some tradeoff equations...
