Abstract
Auger electron spectroscopy (AES) and scanning low-energy electron probe (SLEEP) techniques have been used simultaneously for correlating electronic and surface chemical behavior of impregnated matrix cathodes. The role of S, Ba, and C has been related to emission poisoning, decay with life, and delayed response after cathode shutdown.This publication has 13 references indexed in Scilit:
