The growth of a sinusodial ``perturbation'' in the surface of a flat plate smoothly accelerated by expanding detonation products has been observed using the Los Alamos high‐energy x‐ray facility. Through modeling with a two‐dimensional elastic

A technique for the examination of the dynamic‐tensile‐strength characteristics of materials is presented. The dependence of tensile strength upon stress gradient, hence stress rate, is demonstrated for Al, Cu, Ni, and Pb. The results were tested

Electron‐beam loading of a single‐cavity standing‐wave accelerator has been investigated experimentally and theoretically for the case of continuous injection over ten cycles. The particular cavity used was a 2.4‐m long right‐circular cylin

An apparatus is described which is based on the technique introduced by Kistiakowsky utilizing the absorption of soft x‐rays to measure densities behind gaseous shock and detonation waves. Experimental conditions leading to the smallest absorption

A high‐current, three‐cavity, standing‐wave linear electron accelerator (PHERMEX) has been designed and built to produce a pulsed bremsstrahlung beam. This beam was desired for use in flash radiography of explosively driven metal configurations

Flash radiographs have been taken which clearly illustrate the formation of both the first and second plastic waves in shocked Sb. The first plastic wave, whose initial pressure and speed are 115 kbar and 3.25 mm/μsec, respectively, is formed in a t
