Abstract :
Summary form only given, as follows. Experiments have been carried out to characterize the conduction phase of the plasma erosion opening switch (PEOS) driven by a fused capacitor bank. Initial experiments with a PEOS cathode (anode) radius of 5 cm (8.9 cm) used magnetic probes to determine the PEOS current distribution and collimated, visible light detectors and Faraday cups to detect the presence of plasma. Results of these preliminary measurements suggest that non-current-carrying plasma is accelerated ahead of the PEOS current channel, in the direction of the load. This plasma must be accounted for when computing the PEOS center-of-mass displacement and may also have some effect on the load performance.<>
