Abstract

Summary form only given. Recently, the 1.5 MW, 110 GHz gyrotron with a new cavity has been tested at MIT. The new cavity (V-2005) significantly reduces ohmic loss and, therefore, it is very promising for CW operation of a gyrotron. The gyrotron with the new cavity has been tested in the axial configuration. The maximum power is 1.67 MW in the design mode TE_22,6, and the corresponding efficiency is 42%, which is consistent with theory. The detailed gyrotron simulations using the code MAGY, developed by the Univ. Maryland and the Naval Research Lab, will be presented. Also new results from the gyrotron including an internal mode converter and a depressed collector incorporated to increase the efficiency will be discussed
