Z-pinch experiments on the UCSD LTD generator.
POSTER
Abstract
Linear Transformer Drivers (LTDs) are based on the state of the art pulsed power generator technology, featuring small footprint, high energy coupling to high energy density loads, low inductance, multi-stage modularity, and potentially high repetition rate [1]. A LTD generator capable of producing up to 1 MA in 150 ns has recently been assembled at UCSD based on a prototype from Sandia National Laboratories [2]. We present the first results from Z-pinch experiments conducted on this machine in both wire arrays and gas puff configurations. The experimental data include machine performance diagnostics, such as monitors for all the spark gap switches and load current probes, and plasma diagnostics such as XUV time-gated and time-integrated images, filtered X-ray photodetectors, time-gated and time-integrated spectroscopy, and laser probing. \begin{enumerate} \item R.
