An experimental campaign was recently completed at the U.S. Naval Research Laboratory’s Mercury pulsed-power facility, where the feasibility of using a 5 MV inductive voltage adder (IVA) as a pulsed photoneutron source was studied. In these experim

Intense pulsed active detection (IPAD) is a promising technique for detecting fissile material to prevent the proliferation of special nuclear materials. With IPAD, fissions are induced in a brief, intense radiation burst and the resulting gamma ray

Multi-petawatt laser systems can produce conditions where quantum electrodynamics (QED) effects are important. The effects can lead to efficient generation of gamma rays and electron-positron pairs, suggesting the possibility of generating intense be

The objectives of this tutorial are as follows: 1) to help students and researchers develop a basic understanding of how pulsed-power systems are used to create high-energy-density (HED) matter; 2) to develop a basic understanding of a new, compact,

SHOCK COMPRESSION OF CONDENSED MATTER - 2019: Proceedings of the Conference of the American Physical Society Topical Group on Shock Compression of Condensed Matter.
Among the most dominant factors in x-ray radiographic image resolution is the radiographic spot size, which is primarily a function of the physical extent of the x-ray source, so the most marked improvements in image resolution come from modifying th

The small community of physicists concerned with flash x-rays, short pulses of intense hard bremsstrahlung with photon energies exceeding hundreds of keV, is always on the lookout for new detector materials and protocols to diagnose such radiation pu

The Aerogel Cherenkov Detector for Cygnus (ACD/C) is a time-dependent, x-ray spectral detector that uses SiO2 aerogels spanning an index of refraction (n = 1.02–1.07) corresponding to a 1.1–2.3 MeV x-ray energy threshold. The ACD/C was developed

Our team at Los Alamos National Laboratory has performed many successful energy-spectra measurements of both continuous and flash, intense radiographic sources with Compton spectrometers. In this method, a collimated beam of x-rays incident on a conv
