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

Level set techniques are numerical techniques for tracking moving interfaces, and have been applied to a wide collection of problems in front propagating and surface advancement. The techniques are robust, accurate, unbreakable, and extremely fast, a

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

The level-set approach of Osher & Sethian to tracking interfaces is successfully adapted to the simulation of a premixed turbulent open V-flame including the effects of exothermicity and baroclinicity. In accord with experimental observations this al

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 consider a problem in which we are given a domain, a cost function which depends on position at each point in the domain, and a subset of points (“cities”) in the domain. The goal is to determine the cheapest closed path that visits each city
