This research program is concerned with the physics and the application of low energy x-ray and associated electron interactions. It has been concentrated upon the sub-kilovolt energy region where the need has been greatest for the development of efficient and precise spectroscopic methods, for the measurement of fundamental interaction cross sections, and for the basic theoretical modeling of certain important x-ray and electron interaction processes as, for example, x-ray induced photo-emission and fluorescence. This work is applied to two areas of considerable present importance and need the development of high efficiency spectroscopic methods that can be effectively applied to the diagnostics of high temperature plasmas--particularly as generated by high power pulsed lasers, electron or ion beams and by exploding wires, for which high temporal resolution as well as high spectral resolution is needed and the testing and application of high-efficiency low-energy fluorescent spectroscopic measurement and analysis for valence and molecular orbital electron energy state studies, for the solid state characterization of surfaces, and for studies of the effects of radiation damage.
