The high-temperature plasma generated by a theta pinch discharge was studied as an emission source for solid samples. Both sample geometry and the discharge fill gas affect plasma formation and subsequent plasma/sample interaction. Ablation and emission from solid samples have been demonstrated for aluminum, tungsten, and stainless steel samples exposed to the plasma. Time-resolved emission data show neutral emission occurring well after cessation of ion and continuum emission. Time resolution therefore removes the limitations of high background and ion line interference, which are associated with high energy discharges. 15 references, 9 figures, 1 table.
