PHERMEX, a Pulsed High‐Energy Radiographic Machine Emitting X Rays, designed and built by members of the staff of the Los Alamos Scientific Laboratory, is a high‐current standing‐wave linear accelerator which generates intense bursts of x rays for flash radiographic studies of explosive‐driven metal systems.

A brief discussion is presented of the need for this device and of some of its design Author: Douglas Venable. The PHERMEX machine is a high-current, MeV, linear electron accelerator that produces very intense but short-duration bursts of brems-strahlung from a thin tungsten target for flash radiographic studies of explosives and explosive-driven metal systems, The facility was built in the early s to complement other hydrodynamics facilities at.

Research on explosives spans more than a century and has involved experimental, theoretical and computational studies. Many excellent text books have been written on explosives including those by Bowden and Yoffe, 1 1. Bowden and A. Yoffe, Initiation and Growth of Explosion in Liquids and Solids (Cambridge University Press, ).Cited by: The Los Alamos Scientific Laboratory radiographic facility, PHERMEX [2], has been used to study the density profile of a detonation wave proceeding up a large block of explosive both with free surfaces and confined by various metal by: 3.

Nevertheless flash radiography has played an important role in diagnosing explosive events, and measurements in shocked solids have given information on high pressure properties up to GPa.2 Information on the techniques employed is given in book^^,^ and conference proceeding^.^ An x-ray source consisting of a linear accelerator for Author: R.J.

Emrich. The technique was reported~ to be applied in a wide variety of investigations which include studies of chemical reactions,2 radioactive material,a ballistics, explosives,melting, materials under short-term stress and X-ray diffraction The large field of applications and the prospects foreseen for flash X-ray radiography made it an Cited by: 1.

This paper explores the Dead Zone (DZ) phenomenon in solid High Explosives (HEs), whereby weaker regions of a detonation shock fail to trigger prompt reaction, leaving behind them isolated pockets of substantially unburned explosive.

A key unanswered question is the extent to which DZs react in the following flow, and whether they contribute a significant amount of energy on timescales Cited by: 2. A method of injection into betatrons, which employs relativistic beams to overcome space charge limitations, is discussed.

The method eliminates the need to modify the betatron with a toroidal. Pulsed High-Energy Radiographic Machine Emitting X-Rays (PHERMEX): Applications To Study High-Pressure Flow And Detonation Waves Richard D.
