Parallelization of Non-Equilibrium Radiation Transport Code

Radiation transport eeects on X-ray line emission are important in modeling spectroscopic-quality, synthetic spectra of mid-and high-Z tracer elements in hot dense plasmas. Plasmas produced in the laboratory are usually in non-equilibrium, i.e. the ion-ization balance and distribution of atomic-level populations are determined by a set of collisional and radiative atomic processes. In these con...

Towards a 3D Space Radiation Transport Code

High-speed computational procedures for space radiation shielding have relied on asymptotic expansions in terms of the off-axis scatter and replacement of the general geometry problem by a collection of flat plates. This type of solution was derived for application to human rated systems in which the radius of the shielded volume is large compared to the off-axis diffusion limiting leakage at l...

Current Status of Hetc-heds Radiation Transport Code Development

One of the hazards faced by crews of spacecraft in space is exposure to ionizing radiation in the space environment. The main sources of these radiations are the trapped radiation in the Van Allen belts, consisting mainly of protons in the inner belt and electrons in the outer belt, the galactic cosmic ray (GCR) background, composed of all naturallyoccurring elements, and solar energetic partic...

Gradient transport processes in E×B plasmas

Various classes of non-quiescent magnetized plasma exhibit anomalous energy and/or momentum diffusivity. In this case, ‘anomalous’ is meant to characterize a transport regime wherein the measured property flux disagrees with classical theory. In most examples anomalous transport is substantially higher than classical expressions predict; it is no different for the Hall accelerator. It has been ...
