Compact Pulsed Power Driver For Research On Energy Transfer And Interface In High Energy Density Plasmas

Abstract

The UC San Diego High Energy Density Physics (HEDP) Group seeks to expand the capabilities of a Linear Transformer Driver (LTDIII) to enable HEDP experiments. A pulsed power driver capable of delivering 1 MA with a rise time of 200 ns into a low inductance load, LTDIII has only been tested with static, short-circuit loads to date, and the device is not presently configured to drive plasma experiments. The construction of a vacuum chamber and a transmission line would allow plasma experiments examining energy (heat and field transfer) in unexplored plasma regimes, specifically: 1) the examination of energy transfer in high beta plasmas; and 2) the exploration of the dynamics of interfaces and mixing in multi-species plasmas. This work will benefit several areas important to the US Air Force Office of Scientific Research (AFOSR) portfolio. It will increase scientific understanding required to predict heat transfer in under-explored plasma regimes. Also, using LTDIII to drive plasma experiments will advance understanding of this type of compact pulsed power device, which has been sparsely used in plasma experiments.
