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