Abstract
Hydrogen Plasma Opening Switch (POS) experiments on Hawk show potential for increasing bremsstrahlung radiation on DECADE. Interferometry indicates that the density of POS plasma is greatly reduced over a large fraction of the interelectrode region (>1 cm out of 2.2 cm) at the time of opening. This low-density region is much larger for the hydrogen POS than for flashover-source POSs used previously on Hawk (and DECADE), and may result in a significantly larger effective vacuum gap, improving the efficiency of energy coupling to loads. Species separation may be responsible for the difference in plasma dynamics between single- and multispecies POSs.
