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.

Ray tracing TID & TNID

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.

Shielding optimization tools

Six faces equivalent thickness

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.

Internal Charging

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.

The Scripting module

Save time in your radiation analysis:

Multi-selection: The user can now interact with a selection of shapes at the same time
Sigma (error) stopping criteria: The user can now define the error criterion, based on which the calculation for each detector will stop
Calculation resumption in Monte-Carlo module: The user can now resume an RMC calculation where it stopped, in order to shoot more particles and get better convergence

Customize FASTRAD® with the scripting module:

Script language: A script language has been integrated into FASTRAD. It allows the user to interact with the main FASTRAD entities, parameterized tasks, deal with custom file format, etc.
Script Integrated Development Interface: The user can write its own script
Script Portfolio: The user can store and quickly execute its own script files

3D Forward Monte Carlo transport for electrons, protons and photons

This module allows to perform calculations using a Forward Monte Carlo algorithm. Primary electrons, protons and photons as well as secondary electrons and photons can be considered. A wide range of source geometries can be defined. Mono-energetic fluxes or continuous energy spectrum can be used for the calculation. Several sensitive volumes can be selected in the 3D model. The results are:

the desposited energy
the dose
the particle fluence

Particle trajectories can be visualized and interaction properties are displayed when a track is selected.

The 3D mapping module allows calculation of deposited energies, transmitted flux and associated errors in sensitive zones. With this tool critical zones can easily be identified.

3D Reverse Monte Carlo for incident electrons and protons

Dose estimate using Reverse Monte Carlo for incident electron and proton flux.

For complex 3D models including different geometrical scales, the dose calculation becomes very time-consuming with a standard (Forward) Monte Carlo approach. The Reverse Monte Carlo approach gives a powerful solution for accurate TID calculation.

Primary and secondary electrons, primary protons and secondary photons (Bremsstrahlung) are taken into account. Point detectors and sensitive volumes can be considered to obtain:

– the deposited ionizing dose: total and per particle type
– the total non-ionizing dose (NIEL tables)
– the transmitted fluence per particle type

TID and TNID calculations are performed in function of the materials assigned to the punctual or volume targets.
Note that the Reverse Monte Carlo method is dedicated to an isotropic environment. Reverse MC module proposes also to visualize the particle trajectories and to display the interaction properties when a track is selected. The 3D mapping module allows calculation of deposited energies, transmitted flux and associated errors in sensitive zones. The Reverse MC module is able to produce one mapping file for all the detectors and sensitive volumes or a merged mapping file including all the selected detectors.
