Effects of thermal spread on the space charge limit of an electron beam
Abstract
An asymptotic analysis is carried out to calculate the effects of a small thermal spread in the injection energy of an electron beam on its space charge limit. It is found that the space charge limit is lowered proportionally to the beam temperature T near T = 0.
