Spectra of sodium K-shell x-ray emission were measured for implosions of sodium-bearing plasmas produced on the Naval Research Laboratory Gamble II pulsed-power generator. Sodium fluoride from a capillary discharge provided the initial plasma for the

The spatial distribution of intense MeV pulsed proton beams over 100 cm2 area is measured with two techniques. An array of carbon‐activation samples gives fluences of 100–400 J/cm2 with 1–2 cm resolution. Continuous distributions with 3–4 mm

Recovery of a pulsed electron beam diode operating in the 50 A/cm2 range has been studied using an inductive storage source producing two∼150 kV pulses with pulse‐to‐pulse separation ranging from 10–500 μsec. The diode cannot instantaneously

Skylab/ATM observations of a disappearing filament near the center of the solar disk are described using XUV and H-alpha spectroheliograms, X-ray filterheliograms, and photospheric magnetograms. The temperature of the coronal plasma as the filament d

When an electron beam (e-beam) is injected into a gas located between two electrodes, a volume discharge, which turns on and off in association with the beam, can be generated. We present a review of the theory and new experimental data for such a di

An intense source of sodium pump-line radiation has been created and used to photopump a neon plasma for application to a pulsed-power driven sodium/neo X-ray laser. Properties of the sodium-pump plasma and the neon-lasant plasma required to optimize

The application of an electron‐beam controlled diffuse discharge to high‐power (>109 W), repetitive opening switches is analytically formulated under a set of assumptions. Basic physics considerations are combined with energy transfer requirement

(1) Highly flare-productive new emerging active regions are characterized by numerous small low-lying loops which frequently show a chaotic pattern. (2) Flare activity in such a region subsides as the chaotic loop structures relax and expand into a b

Inertial confinement fusion using light ion beams requires fast rise time, high power drivers. One technique to enhance a conventional pulsed power generator is to use a plasma erosion opening switch (PEOS) between the generator and the ion diode. Id
