Abstract :
Summary form only given. The ACE 4 high current (>3 megamp) plasma opening switch (POS) uses a high density (>10/sup 15//cc) plasma to achieve microsecond conduction periods. During the conduction phase, a MHD snowplow process is dominant. During the opening phase, less-well-understood processes (Hall, erosion, etc.) seem to be operative. We report here on new measurements meant to help diagnose the opening phase.
