Analysis of the pinch characteristics in a miniaturized repetitive plasma focus device


In this article, the experimental results of pinch characteristics in a miniaturized (20 J) repetitive Mather-type plasma focus device (SORENA-1) have been presented. Argon, neon and deuterium were used as working gases, and variations of pinch characteristics such as pinch time tp, negative spike height hp, pinch duration dt with working conditions (different gases, initial pressures and discharge voltages) were described and analyzed.
