Raman Scattering as a Diagnostic Technique for Cathode Characterization.

Abstract

The feasibility of using the optical technique of Raman scattering to determine the chemical composition of cathode surfaces has been investigated. Reference Raman spectra have been obtained for many of the chemical compounds expected to be present at the surface of dispenser cathodes. In addition, spectra obtained from 5-3-2 impregnant and several cathode surfaces are presented. The potential advantages of the approach are discussed.
