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...
متن کاملTowards 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...
متن کاملCurrent 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...
متن کاملParallelization of Neutron Transport Code ATES3 on BARC’s Parallel System
A Neutron Transport Code ATES3 (Anisotropic Transport Equation Solver in 3D), which was developed at BARC for the deterministic solution of 3D steady-state neutron transport problems, has been parallelized using Message Passing Parallel Programming model on BARC’s ANUPAM Parallel Supercomputer. The most time consuming step in the code ATES3, which is transport sweep, was made parallel using thr...
متن کاملModelling Radiation Transport in Voxel Geometries with the Monte Carlo Code Mcnpx
Numerical methods for the simulation of radiation transport, in particular Monte Carlo techniques, are playing a fundamental role in the field of dosimetry for radiation protection. For the last 30 years or so, reference quantities have been since about 30 years calculated relying on mathematical analytical human phantoms representative of the standard man. These calculations, in large part bas...
