Hybrid X-pinch Experiments on a MA Linear Transformer Driver*

X-pinch experiments have been conducted on the Linear Transformer Driver (LTD) at the University of Michigan. The x-pinch consists of a single wire separated by conical electrodes between two current return plates. The LTD was charged to $+$/-70 kV resulting in approximately 0.5 MA passing through a 35$\mu$m Al wire. Multiple, short x-ray bursts were detected over the 400 ns current pulse. Ultimately the x-pinch will be located in parallel with a planar foil in order to backlight the Magneto-Rayleigh-Taylor instability. A smaller 100 kA driver is also in development and may be used to independently energize the x-pinch. The x-pinch chamber has been constructed and the results of these experiments will be presented. \\[4pt] *This work was supported by DoE award number DE-SC0002590, NSF grant number PHY 0903340, and US DoE through Sandia National Labs award numbers 240985 and 76822 to the U of Michigan.
