Secondary Electron Emission of Certain Ceramics and Antidynatron Coatings

Abstract

The possibility of reducing the coefficient of secondary electron emission of aluminum oxide ceramics by applying coatings of boron nitride-vanadium oxide to their surfaces was investigated. Data are presented showing that the values of the coefficient for these ceramics, used in power taps of powerful superhigh frequency devices are dangerously high, with respect to increase in secondary electron discharge. Coatings with various proportions of boron nitride and V2O5 effectively reduce the coefficient of secondary electron emission.
