Abstract:

A quasioptical gyroklystron for generating high power quasioptical radiation. A mildly relativistic electron beam gyrating in a static magnetic field is passed through a first open mirror resonator where a small change in the transverse electron energy takes place (either an increase or decrease depending on the relative phase between the electron gyration and the resonator wave fields). This small change than leads to slower (or more rapid) gyration of those electrons that have gained (or lost) energy in the first resonator. The length of the drift region between the first and a second open mirror resonator is adjusted so that rapidly gyrating electrons overtake slowly gyrating ones at the entrance to the second resonator. Thus the particles arrive at the second resonator strongly bunched in gyration phase. The fields in the first resonator are generated by feedback of a small amount of energy from the wave mode in the second resonator with a. pi.
