Abstract

The Hawk plasma opening switch was examined spectroscopically to determine the role of contamination from plasma-surface interactions during the conduction phase. The switch was operated using the inverse pinch plasma source with H2 gas, so that the detection of carbon provides direct evidence that impurities from material surfaces have been incorporated into the switch plasma. A visible and UV range monochromator was used simultaneously to monitor sets of lines from C in each spectral range. Initial analysis showed that the impurity emission was significantly higher near the anode.
