Depressed collectors for high-power gyrotrons

An analytic and numerical study of the feasibility of depressed collectors for gyrotrons for accelerator applications is discussed, and a specific design for a 10-GHz 30-MW gyroklystron is realized. The conclusion of the study is that depressed collectors are feasible for gyrotrons of interest for accelerator applications (i.e. P >
