Abstract
Effects of thermal-velocity spread on the noise figure of a traveling-wave tube have been computed by extending a method of Hahn. To accomplish this, it has been necessary to work out a new theory for the diode-drift tube and traveling-wave tube that includes the effect of the thermal-velocity spread at very high frequencies. Some computations are given for conditions met in practice.This publication has 8 references indexed in Scilit:
