DEFINITION
Classification: 331/83
(under subclass 81) Subject matter wherein the means controlling the beam includes at least two distributed parameter devices of the cavity resonator type, the resonators being provided with apertures, the beam of particles being directed through the apertures of the resonators in succession, exciting the resonators into oscillation. The first resonator causes bunching of the particles passing therethrough, the bunched particles then travel in a field-free region where further bunching occurs and then the bunched particles enter the second resonator giving up their energy to excite it into oscillation, a positive feedback loop from the second resonator to the first
resonator causes sustained oscillations to be generated.
