Abstract : An improved gryrotron oscillator or gyrotron amplifier has a plurality of strong-field magnetic arrays disposed along the length of the device. Each magnetic array comprises n electromagnets, the windings of which are arranged so that the polarity of the electromagnets alternates around each array. Further, the polarity of the corresponding magnets in successive arrays alternate axially along the device. The strong-field magnetic arrays focus and reshape the electron beam within the gyrotron, thereby increasing the efficiency of the device. Permanent magnets may be used in lieu of electromagnets but offer less control. (Author)
