Abstract
We examine analytically the linear operation of relativistic traveling wave tube amplifiers. In this regime it is found that the maximum gro wth rate occurs at a beam velocity below that expected on the basis of resonance with the cold dispersion relation of the slow wave structur e. The maximum growth rate can be much larger than that at the resonan ce condition. These results have significance when extending Pierce's theory to traveling wave amplifiers driven by relativistic electron be ams.
