Abstract

Summary form only given. A 70kV, 100kA compact pulse generator (0.7m × 0.9m × 0.3m) has been constructed and successfully tested with a resistive load using a linear LTD-type capacitor-switch configuration. The generator consists of 6 bricks connected in parallel, where each brick contains two oppositely charged capacitors (+/-70kV, 40nF) and a low inductance L-3 spark-gap switch (93nH). The bricks are connected to the load through a parallel plate transmission line. The generator is designed to drive a hybrid x-pinch to serve as a diagnostic for planar foil ablation experiments on the 1-MA LTD at the Michigan Accelerator for Inductive Z-pinch Experiments (MAIZE) facility.[1,2] The hybrid x-pinch diagnostic consists of a 35-50μm Al or Mo wire between two conical tungsten electrodes and will be used as a backlighter in addition to the current 775nm Ti:sapphire laser. The construction of the hybrid x-pinch chamber and transmission line is currently underway. In addition, the generator may be used to create external magnetic fields for magneto Rayleigh-Taylor (MRT) experiments on the 1-MA LTD. Preliminary results of generator characterization will be presented.
