Magnesium-coated aluminum wire array Z pinch plasmas have been tested on a 4-MA, 6-TW pulsed electrical generator. A mixture of 80% aluminum and 20% magnesium is observed to maximize the radiated kilovolt x-ray yield at \ensuremath{\ge}50 kJ, which i

Frequently, the most energetic radiation emitted in abundance from a Z pinch is photons from the H- and He-like stages of the load element(s), i.e., the K shell. Consequently, the K-shell spectroscopy of Z pinches is well established and often used f

The non-uniform acceleration of partially vaporized and ionized wires in wire array loads results in precursor plasmas that assemble on-axis and soften the subsequent implosion of the remaining mass. One micron thick Al ribbons with an anticipated va

The vapor phase separating the initial solid state from the final plasma state of wire loads in pulse power devices is often assumed to be very short lived and of no consequence to the subsequent load implosion for fast current pulses. However, resea

Although Thomson scattering of laser light from plasmas has become a widely accepted laboratory diagnostic technique, many experiments involving high‐density low‐temperature plasmas suffer from a masking of the incoherent scattered radiation by b

Differential charging of dielectric surfaces on spacecraft has received much attention in recent years because of the possible damage to spacecraft systems resulting from electrical breakdowns. Teflon presents a long term hazard because it can retain
