Development of the resonant-cavity virtual cathode and large-orbit gyrotron high-power microwave sources
At Los Alamos National Laboratory, research is continuing on the development of both the resonant-cavity virtual-cathode source and the large-orbit gyrotron high-power microwave source. The resonant-cavity virtual-cathode development effort has succeeded in demonstrating narrow-band single-mode operation of this typically wide-band source. This is accomplished by supplying feedback to the oscillating virtual cathode with a resonant-cavity structure. The large-orbit gyrotron effort is developing a method for efficiently coupling the microwave power from the device so that it can be easily used as a high-power microwave generator for accelerator applications. A repetitive pulse capability is also being developed for both microwave sources. Experimental results are presented in this paper. 3 refs., 7 figs.
