Investigations of Ionic Species in High Pressure Cesium Discharges.
Abstract
Ion sampling measurements were made on cesium plasmas for normalized pressures from .0001 to 1 Torr using dc as well as rf excitation. For dc discharges, sampling was undertaken through both the anode and cathode. The major cesium ions observed were Cs(+), Cs2(+), and Cs3(+). Measurements were made of the ion current ratios, I(Cs2(+))/I(Cs(+)), and I(Cs3(+))/I(Cs2(+)) as a function of normalized pressure. Comparison of the observed dependencies with those predicted using steady state-kinetics provides estimates of the rate coefficients. (Author)
