Abstract
In this paper, the cathode evaporation rate during current emission is measured. The quartz crystal microbalance (QCM) method is used to measure the thickness of the deposited active materials in vacuum. The principle of the QCM is that a frequency shift is introduced when evaporated materials are deposited on the crystal. The evaporation of active materials is measured at different cathode temperature in which the cathode do not emit.
