FASTRAD® Modules, discover all the functionalities:

Radiation CAD interface & data-exchange

Simplified configuration, limited to creating and handling 3D radiation models, allowing to import and export entire STEP object characteristics.

A graphical user interface will allow you to create and handle geometries:

  • Insertion of simple shapes (box, slab, cylinder, cake, sphere, cone, triangular prism, elliptical cylinder and torus, extruded trapeze).
  • Viewer 3D / 2D + objects handling (rotation, translation, etc. )
  • A material definition interface with a database
  • Hollowing out and merge simple shapes and also shapes coming from the imported .STEP file
  • Advanced display and screenshot tool
  • Mass calculation
  • Material management tool (display, replacement, list cleaner)
  • Detector handling tools
  • Advanced search tool
  • Measuring tool
  • Clipping plane

 Ray tracing calculation 

Create solids using points in the 3D model and perform essential calculations: sector analysis (Minimum and Slant Ray tracing), equivalent thickness, ray view and shielding mapping.

Dose calculation by sector analysis on any Fastrad model containing simple shapes or tessellated volumes (coming from STEP or IGES format files).

Two calculation methods are proposed:

  • The slant one (associated with solid sphere Dose Depth Curve)
  • The ‘minimum path’ method (with a shell shpere Dose Depth Curve)

This interface is dedicated to the calculation of the Displacement Damage Equivalent Fluence (DDEF) and TID in sensitive areas.

Scripting module & Monte Carlo calculations

A script language, allowing the user to interact with the main FASTRAD entities, parameterized tasks, deal with custom file format, etc. This service gives you also the keys to the most efficient Monte Carlo calculation: Both Forward and Reverse Monte Carlo calculation are available. The Monte Carlo is based on actual physical interactions of particles with matter. It considers the material composition and the particle behavior allowing to get a higher level of accuracy. The calculation can be run on several threads (parallelization) to decrease the computation time. The two calculations, Forward and Reverse MC, can be launched by command line (batch file) with the definition of several computation parameters in optional argument (number of shots, output file, number of threads,etc.) for a given ‘.ray’ model.

In the simple Internal Charging analysis, FASTRAD calculates the net electron flux which is stopped between two point detectors in a dielectric (pA/cm²).

In the advanced Internal Charging analysis, FASTRAD computes five quantities: the incident electron flux (pA/cm2), the charge deposition rate (total) (C/m3/s), the charge deposition rate (primaries) (C/m3/s), the dose rate (rad/s) and the deposited energy (MeV). These quantities are only computed for volumes.

These calculations are based on the Monte Carlo particle transport method.
