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.
In this paper the results of dielectric properties measurements of FC-75 (Fluoro Carbon-75) are presented, which is used in the double disk RF window of gyrotron as a coolant. The dielectric constant, the dielectric loss, the a.c. conductivity and the relaxation time are measured from 1 GHz to 50 GHz. The measurement procedure is based on reflection method. The measurements were performed by dielectric...
In this paper, the design of a triode-type magnetically tunable magnetron injection gun (MT-MIG) is presented for 1-MW 110-, 120-, and 127.5-GHz-frequency gyrotrons with the various operating modes. Some basic equations relevant to the problem available in the literature have been used to obtain the preliminary design. Computer simulation has been performed by using the commercially available code...
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...
A weakly tapered interaction cavity has been designed to excite TE03 operation mode at the fundamental harmonic number for 42 GHz, 200 kW gyrotron. A software code GCAVSYN has been developed to synthesize cavity geometry and selection of operating mode. The cold cavity analysis and beam-wave interaction were carried out using commercially available PIC code MAGIC. An axial output power above 200 kW...
