Investigation of Electron Impact Processes Relevant to Visible Lasers

Abstract

The emphasis of the work during the reporting period has been placed upon the design and optimization of a glow discharge source of metastable atoms which was subsequently installed in the electron spectrometer system. As a consequence of signal-to-noise problems and long term stability limitations encountered with the energy loss spectroscopy the experiment has been modified and a fluorescence diagnostic substituted for the electrostatic electron energy analyzer. Preliminary experiments involving electron-ground state atoms have been performed in order to evaluate the sensitivity of the fluorescence technique. Numerous experimental modifications have been performed in order to reduce the principal source of noise, namely fluorescence emission from the discharge source.
