Abstract
The effect of an axial energy spread on the linear pin in backward wav e oscillators is considered. The electron beam is assumed to be mono-e nergetic with a momentum spread. The results obtained show that for a Gaussian distribution in the beam axial momentum, the gain of a backwa rd wave oscillator falls off rapidly when the momentum spread is of th e order of 2.0% for a given set of parameters corresponding to backwar d wave oscillator experiments.
