Fx 25 Fx 100 Propagation Experiments Amrc R 391 by Ekdahl Wright Hughes Godfrey Bostick (1 results)

Velobound. Condition: Very good. Presumed First Edition, First printing. Various paginations (approximately 160 pages). Illustrations (some with color). References. Appendices (these include six AMRC reports on such topics as FX-100 Propagation Experiments, Small Aperture Faraday Cup, Monte Carlo Electron Beam Transport in Air, Particle Simulation of an FX-100 Beam, and Optical Emission from Intense Relativistic Electron Beam Excited Air). C. A. Ekdahl is believe to be the same individual who later had a distinguished career at the Los Alamos National Laboratory and was strongly associated with the DARHT facility. A program of extensively diagnosed experiments to investigate the physics of intense relativistic electron-beam propagation in low-density air was in progress using beam generators at the Air Force Weapons Laboratory. The primary objectives of this research were the rate of erosion at the head of the beam, and to investigate resistive instabilities, such as the hose and hollowing modes, that limit the transport of beam energy over significant distances. The first year tasks of delineating the pressure range for maximum energy transport and measuring the temporal evolution of the current density profile of the beam produced by the FX-100 had been accomplished.
