Inserting a thick slab of porous dielectric (e.g., ceramic honeycomb) in front of the emitting surface of a large-area planar diode improves the electron beam emission uniformity, decreases the beam current rise and fall times, and maintains a more c

An optical method for measuring scattered light, namely by analyzing the transmitted light, is used to characterize the optical properties of low-density foams that are candidates as targets for inertial confinement fusion. This method allows us to s

Optimum pumping of krypton fluoride (KrF) lasers requires electron beams that are stable against the transit time instability and spatially uniform. Eliminating the enhanced current density (beam halo) along the edges of a large area homogenous elect

There has recently been a revival of an old controversy over whether Ampere’s original law of force between current elements is to be preferred over the more familiar and universally used Biot–Savart–Lorentz law. Although it is agreed that the

A novel intense source of 2.45 MeV neutrons is described. Exploratory experiments with deuterated polyethylene fibers in an x‐pinch configuration have been performed using 370‐kA, 80‐ns current pulses. Up to 4.5×108 neutrons per pulse have bee

We have devised a simple experimental technique for determining the effects of a 90° bend in a coaxial pulse forming line. A time domain reflectometer (TDR) is used to inject a fast rising signal (

The NRL ZFX Facility is being used to form dense Z pinches from single fibers composed of cryogenically frozen deuterium (D2) or deuterated polyethylene (CD2). Fiber diameters range from 40 to 125 μm. Maximum current through all these pinches has be

Particle-in-cell simulations are used to model large-area, electron-beam diodes that pump krypton–fluoride (KrF) laser cells. The simulations include models for following the energy loss and scattering of beam electrons in foils, gas, and support s

A rotating relativistic electron beam, charge but not current neutralized and exceeding the Alfven limit, has been propagated down a closed metal tube in the absence of an external guide field. The radial equilibrium is determined by the self-fields
