A Determination of the Symmetric Charge Transfer Cross Sections for Ar^+ and Xe^+ at Ion Thruster Conditions.
Abstract
Symmetric charge transfer cross sections for Ar^+ and Xe^+ in their respective neutral gases are determined in a guided ion beam instrument for collision energies up to 400 eV. The cross sections are determined using two independent methods. In the first method, attenuation of the primary ion beam in the presence of the neutral gas is measured. The second method is a time-of-flight technique in which both the primary ions and charge transfer product intensities are measured based on their temporal separation. The results are compared to previous experimental work as well as to theoretical calculations.
