R. Montoya/Sandia National Laboratory
The Z Accelerator at Sandia National Laboratories, which is 34 m in diameter and 7 m high. A capacitor bank, just inside the outer diameter, can be charged to 22 megajoules to generate a current pulse with a peak of ∼25 mega-amps and a rise time of ∼100 to 500 ns. Important thicknesses of the aluminum and quartz drive plates and water samples (see supplemental information in Ref. ) were a few 100 microns; the rear quartz window was a few mm thick. The sparking in the figure is caused by some power leakage from fast switches.
