Investigations of magnetic field diffusion and plasma resistivity in 12-cm-diameter triple-gas-puff Ar Z-pinch implosions were carried out by using planar laser-induced fluorescence (PLIF), a laser shearing interferometer (LSI), and a laser wavefront

Bremsstrahlung from high-power electron-beam diodes increases and becomes spatially more uniform when the tantalum anode is first pulse-heated to remove gas from the surface and interior, and then pulse-heated again to white hot just prior to and dur

High-current (1–3 MA) reflex triodes are being developed as intense pulsed sources of moderate energy (200–1200 kV endpoint) bremsstrahlung. The triode consists of three coaxial electrodes: two hollow cylindrical cathodes and a flat anode foil be

Saturn is a pulsed power accelerator consisting of 36 parallel modules producing 10 MA at 1.7 MV in a 40 ns power pulse[1]. Saturn is built to operate in negative polarity. Two methods of inverting the polarity in vacuum and driving up to 2.5 MA into

Calculations to determine the dose scaling from a low-impedance (∼1 Ω) reflex triode with voltage and current have been performed. These calculations use the particle-in-cell code LSP1 to follow the charged particle dynamics in a reflex triode. A

An extension of the US Naval Research Laboratories' model for plasma erosion opening switch (PEOS) operation is proposed (see P.F. Ottinger, et al., 1984). This model differs from previous models in that it includes a simplified 1-D plasma sheath at

A fast Marx (220 kJ, 450 nH, 675 kV) has been developed as a driver for an electron beam generator. This generator uses an inductive store with an opening switch to compress and amplify the power pulse. The 220 kJ Marx consists of four parallel 55 kJ
