Investigation of Electron Impact Processes Relevant to Visible Lasers
Abstract
During this contract period the noise background in the electron spectrometer has been reduced to an acceptable level. Two parallel efforts are currently underway to investigate and optimize metastable rare gas atom production. A glow discharge source has been constructed which produces of the order 10 to the 8th power/cu.cm. argon metastable atoms within the collision volume intercepted by the electron beam. Electron scattering experiments are currently underway using this source. In addition the ion current capabilities of a Duoplasmatron ion source are being explored with a view to potential application to a charge transfer source of metastable rare gas atoms. The projected metastable density achievable from such a system should be of the order 10 to the 10th power/cu.cm. which represents two orders of magnitude improvement over the presently employed glow discharge source.
