Title: Excitation and ionization of ions by electron impact. Technical progress report, September 1, 1977--May 31, 1978

Abstract

This effort is devoted to the measurement of electron impact collision processes of importance in controlled thermonuclear research. Electron impact, single and multiple ionization of ions and charge exchange processes are being studied. A program to develop ion sources for future collision experiments is also included. Preliminary measurements of the electron impact triple and quadruple ionization cross sections of Pb/sup +/ ions have been completed. Measurements were made over the range of electron energies from the respective thresholds to 1000 eV. A hollow-cathode discharge type ion source and associated m/e analyzer has been constructed. A charge exchange apparatus suitable for the measurement of electron capture and stripping cross sections of selected singly charged metallic ions and neutrals is being designed. This apparatus will be employed with the hollow-cathode ion source module. A Penning Ion Gauge (PIG) type ion source of multiply charge ions is in continuing development.
