A gigawatt-class nonlinear transmission line based electron beam driver is experimentally demonstrated. Four experimental series, each with a different Marx bank charge voltage (15, 20, 25, and 30 kV), were completed. Within each experimental series,

The use of additive manufacturing techniques offers the potential to rapidly fabricate complex insulator designs; however, the lack of dielectric strength data for many of the currently available printable plastics limits the usefulness of these mate

The 100 ns, 20 MA pinch-driver Z is surrounded by an extensive set of diagnostics. There are nine radial lines of sight set at 12° above horizontal and each of these may be equipped with up to five diagnostic ports. Instruments routinely fielded vie

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

Argon gas puff experiments on a 3–4 MA generator show that the K‐shell x‐ray yield is optimized for a 2.5 cm initial diameter and 110 ns implosion time. By varying the driver current, the K‐shell yield varies from 13 to 18 kJ following a curr

The K‐shell x ray yields from argon gas puff Z pinches are observed to increase from 3.5±1.0 kJ to 13±1.0 kJ when inwardly tilted nozzles are used on a 6 TW, 4 MA generator. This increase is associated with the elimination of the zipper effect an

Implosions of 2.5‐cm‐diam neon gas shells on a 1.2 μs quarter‐period, 3 MA driver, FALCON, have produced no more than 7.6 kJ of kilovolt neon K‐shell radiation. The incorporation of a plasma opening switch produces faster current pulses: up
