Abstract
Plasma Opening Switch (POS) experiments to support Sandia National Laboratories PBFA II ion beam accelerator were conducted on Maxwell Laboratories Blackjack 5 accelerator. The first experiment tested an improved flashboard plasma source to generate a uniformly opening POS. The results showed that the J X B force caused plasma motion into the diode load region prior to the opening of the POS. Plasma motion was inferred by comparing experimental data to circuit models which used a variable resistance POS and a variable inductance (L-dot) term. The L-dot term was necessary in the model to reproduce the experimental results.Keywords
