Diagnostics for gas puff experiments on~a~Linear Transformer Driver (CESZAR)

POSTER

Abstract

The CESZAR is a low inductance compact (2m diameter) pulsed-power generator designed to provide up to 1MA of current in 160ns. First experiments on the generator are carried out with a hollow single shell~Ar~gas puff, with the goal of measuring the energy coupling in a low inductance system.The diagnostic suite on these experiments includes filtered photodiodes, laser schlieren imaging and interferometry, spectroscopy, and time-gated XUV pinhole imaging. The temperature and density information is extracted to determine energy coupling. A comparison of experimental results with MHD modeling will be presented to show energy coupling in low inductance system.
