Abstract
During tests of a megawatt-class 140 GHz gyrotron for the fusion experiment Wendelstein 7-X, a window RF arc was documented with a high-resolution spectral measurement system. The arc event coincided with strong perturbations of the nominal cavity mode TE-28,8 and a final mode switch to a neighbor mode. Simulations using a self-consistent interaction code (SELFT) have reproduced the main features of the event and provide additional information on the development of the modes during the window RF arc.
