New thermal calculations have been performed for artificially grown diamond output windows produced by chemical vapor deposition (CVD) installed on 110 GHz 1 MW gyrotrons. These results can be compared with infrared (IR) monitoring of the windows during 5 s pulses. A new prototype depressed collector gyrotron with output power in excess of 1.0 MW at 110 GHz is expected to be tested to full parameter operation at the DIII-D facility. Predicted maximum temperature and temperature profiles are presented based on the characteristics of the particular diamond disk installed on this gyrotron and the model.
