Sandia National Laboratory's z accelerator, a pulsed power facility in operation.
a time-exposure photograph of electrical flash-over arcs produced over the surface of the water in the accelerator tank as a byproduct of z operation. These flash-overs are much like strokes of lightning. The z pulsed power accelerator at Sandia, which began operating in September, 1996, is the world's most powerful and efficient laboratory x-ray source. It is a modified version of the PBFA ii accelerator which was used until 1996 for light ion fusion research.
