The effect of temperature and discharge power of ion-plasma deposition of molecular sputter-deposited oxide microcathodes (MSOC) on their emission activity has been experimentally investigated. The elemental composition of a thin coating of MSOC has been studied using Auge electron spectroscopy (AES) and X-ray fluorescence analysis (XRF). The effect of the atmosphere and residual gases on the operation of microcathodes is shown. Keywords: molecular sputter-deposited oxide microcathode (MSOC), emission characteristics, durability, work function, electrovacuum device (EVD).
