We present short circuit and initial plasma loads on a new 750 kA generator at UC San Diego. Rama is designed to have a risetime of ~1.2μs at peak current, but each of the 6 switches are triggered independently using a new spiral generator unit developed at Imperial College London. This provides significant pulse shaping abilities, and allows a arrange of loads including wires and liner loads to be driven. Gated XUV self-emission and interferometry data will be presented along with Thomson scattering, and these will be compared to 3D simulation work.
