Abstract

In this work, an extensive design study of a 200-250 kW, CW gyrotron operating at 170 GHz, for plasma heating in an experimental Indian Tokamak is presented. Mode competition and mode selection procedures have been carried out for various candidate modes to choose a probable cavity operating mode. The present study includes cold cavity and self-consistent design calculations. The initial results are indicating that an output power of over 250 kW can be achieved at 170 GHz operating with higher order asymmetric volume modes.
