Popis: Because of the inherent advantages of gyrotrons, such a source is expected to be able to produce significantly higher power at high frequencies than that possible with a linear beam tube. A 10 GHz, 30 MW gyroklystron is being developed at the University of Maryland to demonstrate this potential. However, it is recognized that the gyroklystron's efficiency is inferior to that of its linear beam counterpart because gyrotrons extract energy primarily from beam rotational motion only. Thus, for high average power systems, a method for enhancing the efficiency is important. Detailed calculations indicate that a depressed collector for the University of Maryland gyroklystron could have a high ( approximately=76%) collection efficiency, yielding a doubling in the overall efficiency of the gyroklystron to 64%. >
