In this paper the design of interaction cavity for 170GHz, 1MW gyrotron is presented. An in-house developed code GCOMS has been used for operating mode selection and mode competition. For 170 GHz, 1 MW gyrotron interaction cavity TE28,7 mode excite as a operating mode at the fundamental harmonic number. The Electromagnetic simulator-MAGIC, a Particle-in-Cell (PIC) code has been used for the cold cavity...
The interaction cavity simulated, designed and fabricated for the 35 GHz gyrotron is verified experimentally. Free space method for the Q value and resonant frequency measurement is used in the experiments. The WR22 waveguide based antenna system, Agilent Vector Network Analyzer are used as the experimental set-up in the cavity measurement. The simulation results for the same cavity are also obtained...
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...
A weakly tapered interaction cavity has been designed to excite TE22,6 operating mode at the fundamental harmonic number for 120 GHz, 1 MW gyrotron. A MATLAB code has been developed to synthesize cavity geometry and selection of operating mode. The cold cavity analysis and the beam-wave interaction were carried out using the commercially available PIC code MAGIC. The output power above 1 MW has been...
