High power test of a wideband diplexer with short-slotted metal half mirrors for electron cyclotron current drive system
Abstract
The wideband high power diplexer has been developed for combining and fast switching of high power millimeter waves generated by a dual frequency gyrotron. The actual diplexer was tested at the frequency band of 170 GHz in low power. After adjusting a resonant frequency of diplexer for the gyrotron frequency, the evacuated wideband diplexer with short-slotted metal half mirrors was tested at an incident power of about 150 kW, a pulse duration of 30 ms and a frequency band of 170.2-170.3 GHz. Any discharge damage was not observed in the diplexer.
