RayXpert Software

RayXpert is a 3D modeling software that calculates the gamma dose rate by Monte Carlo. Compatible with Windows, RayXpert allows Monte Carlo precision while taking advantage of a user-friendly « push-button » graphical interface. A series of tools simplifies the scenario management (geometry, sources, etc.) and the modeling and calculation steps. For example, the simulation parameters are all saved, maximizing the recalculation. All these features assist the user in his analysis, for a precise, efficient and rapid work in the field of Gamma radiation.

3D Import and Design

The interface quickly enables the user to create realistic 3D models, firstly by combining simple solid shapes (CSG), and secondly by importing 3D models made with standard CAD software (CATIA, SolidWorks, Pro-E, AutoCad,etc.).

Calculation

The particle tracking in the 3D structure is calculated with the Monte Carlo method.
RayXpert deals with photon, electron and positron transport in particular

Multi-source and multi-detector

Several sources and detectors can be simply and simultaneously defined. A completely automated biasing is proposed to accelerate the complex geometry convergence.
The results are the equivalent dose rate (DED H*(10) of the CIPR74) and the photon flux at the detector level.
A calculation window allows you to monitor the DED value and its error rate for each detector, during the simulation.

Validation of results

Comparisons with MCNPx 2.7.0 allowed us to validate photon transport and secondary particles through different materials (concrete, lead, aluminium, nylon,etc.), and for several sources (Co, Cs, Eu, etc.).
These tests also allowed us to validate the dose due to scattered radiation in a 3D scene.

3D Mapping

The Cartography module enables the user to create automatically a mesh of virtual detectors (mesh Tally) allowing to visualize the doses, flux, deposited energies and associated errors in 3D everywhere in the model.
