A low inductance linear transformer driver for exploding wire experiments

We present results from the first wire array experiments performed on a new 250 kA linear transformer driver (LTD) generator installed at UCSD. The LTD design represents a new approach in the field of exploding wire experiments. Importantly this driver creates the opportunity for repetition-rated experiments, which are unfeasible for traditional Marx driven systems. We will discuss the design of the high voltage power feed and experimental systems, as well as the performance of the generator in different load and charge voltage configurations. In addition, quantitative measurements of the plasma density evolution in cylindrical wire arrays will be shown, and compared to results from an 80 kA system in the same laboratory. A discussion of the scaling of these experiments relative to analytical theory will be given.
