Cerenkov rebatron radiator [chə′reŋ·kəf ¦rē·bə‚trän ¦rād·ē‚ād·ər]
(electronics) Device in which a tightly bunched, velocity-modulated electron beam is passed through a hole in a dielectric; the reaction between the higher velocity of the electrons passing through the hole and the slower velocity of the electromagnetic energy passing through the dielectric results in radiation at some frequency higher than the frequency of modulation of the electron beam.
