Abstract
Some simple methods of preparing MgO thin films on Mg–Ag alloy with high secondary emission ratios are discussed. The oxidation procedure and a discussion of the underlying phenomena are presented. Films with a secondary yield of 12 at 600 v may be produced by oxidation in either oxygen or carbon dioxide. Results of a study of some of the factors influencing the life of a secondary emitter are given. These include the effects on the secondary emitting characteristics of evaporation products from an oxide‐coated cathode and the deterioration of the thin film under electron bombardment.This publication has 5 references indexed in Scilit:
