Investigation on a 170 GHz/230 GHz Dual Mode Megawatt-class Gyrotron For CFETR

Abstract

in this paper, we present an investigation on a dual-frequency dual-mode megawatt-class gyrotron. The gyrotron can operate at frequencies of 170 GHz and 240 GH with the corresponding operating modes TE33.12 and TE44.16, respectively. In the analyses, the startup scenarios for the operating modes have been investigated by an in-house, developed, multi-mode, time-dependent code. The simulations result show that the output power of the gyrotron can reach about 1 MW at two operating frequencies with corresponding operating conditions.
