PIM is a water filled Blumlein connected, in parallel, to one or two 1.5 MV, cavities which inductively add voltage on a high impedance vacuum transmission line to a load diode operating at 1-3 MV. The radiographic performance of this IVA pulsed power machine depends on the inductive rise-time of the Blumlein switches. Selection of either one or two simultaneously closing switches on PIM was used...
Mercury became operational in a stepwise manner to test the machine components after modifications and reassembly at NRL. To avoid damaging the MIVA, extensive testing of the laser and PFL output switches was performed using dummy loads. Finally, the PFLs were connected to the MIVA and Mercury was fired into a simple cylindrical diode load with a Marx charge voltage up to 75 kV. Measured MIVA currents...
The ZR refurbishment project [1] at Sandia National Laboratories (SNL) required a set of diverter switches to protect the Marx generators and intermediate storage (IS) capacitors from Marx pre-fire and/or laser triggered output switch (LTS) no-fire. Thirty-six such diverters, one for each Marx-IS set, will need to operate reliably over the full range of Marx charge voltages and LTS anticipated closure...
This paper describes an induction voltage adder (IVA) being designed by Titan Pulse Sciences Division (TPSD) for AWE Aldermaston, UK. This IVA will be used to power the radiography sources in AWE's planned three-axis Hydrodynamic Research Facility (HRF). TPSD will provide the IVAs and AWE will provide the radiographic diodes. The full IVA will in its initial configuration deliver a 14 MV, 110 kA,...
