VISRAD Major Features

Supports convenient generation of grids for a variety of 2-D and 3-D primitives, as well as pre-configured cylindrical hohlraums and halfraums, and tetrahedral hohlraums.
Provides capability for surface removal (e.g., drilling holes in cylinders).
Conveniently provides views from diagnostic ports or any user-specified position.
Provides easy-to-use target building capability. Object positions and orientations can be specified in coordinate system of target chamber or any other target component.
Supports use of object-dependent material properties for:
 
Reflection of radiation (albedos).
Reflection of laser light (glint).
X-ray conversion efficiencies.
Provides 3-D interactive graphics for:
 
Target grid setup.
Laser beams and/or target component power sources.
Temperature and radiation flux distributions.
Includes power source modeling for:
 
Laser beam systems.
Self emission from target components.
Provides for easy viewing of laser beams intersections with target components.
Includes accurate algorithms for computing configuration factor integrals.
View factors include effects of occultation (i.e., blocking of light by intervening surface elements).
Provides easy-to-use set up of laser beams:
 
Pointing and focusing specified in coordinate system of target chamber or any target component.
Beam clustering allows convenient setup of beam parameters by group.
Shows results for individual surface elements chosen by easy mouse clicks, including temperatures, fluxes and incident spectrum.
Interfaces with other Prism software tools:
 
HELIOS, providing time- and frequency-dependent incident radiation flux data.
PrismPLOT: a graphics tool for generating line plots, color contour plots, and 3-D surface plots.
SPECT3D, providing time- and frequency-dependent incident radiation flux data.
