Field Precision Releases Xenos: Software Suite for X-ray Simulation

The diagram shows how the programs communicate to form an integrated package. The system geometry is defined in the interactive graphical environment of Geometer. MetaMesh uses the information to create conformal meshes of hexahedron elements for the solution programs. The same or different meshes may be used to define 1) electrodes and dielectrics for electrical field calculations (HiPhi), 2) coils, iron and permanent magnets for magnetic field calculations (Magnum), 3) elements and compounds for Monte Carlo radiation transport (GamBet) and 4) solid materials for thermal transport (HeatWave). From this point, there are several options:

* GamBet can import field information from HiPhi and Magnum. In this case, electron and positron histories are influenced by Lorentz forces as well as material interactions.
* GamBet can transfer information to OmniTrak to trace orbits of particles generated in a target (i.e., a positron beam).
* Field information from HiPhi and Magnum can be transferred to OmniTrak to design electron guns and transport systems. The resulting beam distributions can then be sent to GamBet to study target interactions.
* GamBet records the spatial distribution of deposited power density. The information is used by HeatWave for static and dynamic thermal simulations.
* GenDist performs statistical analysis of particle distributions from OmniTrak and Gambet.

Xenos includes a parallel set of programs for 2D calculations. There are several pathways for interactions between the 2D and 3D programs.

The following is a small subset of the calculations that may be performed with Xenos

* Spatial resolution of X-ray imaging systems.
* Clinical dose distributions with multiple electron or X-ray beams.
* Heater power for a thermionic cathode.
* Clinical dose distributions with multiple electron or X-ray beams.
* Peak electric field in a high-voltage feethrough.
* Calibration of beam diagnostics.
* Shielding requirements and temperature profiles for an electron-beam welder.
* Resolution limits in an X-ray imaging system set by photon scattering.
* Design of bending and focusing magnets for a beam line.
* Positron production and capture in an optical system.
* Aberrations in solenoid or quadrupole lenses.
* Beam perturbations from surrounding iron structures.
* Space-charge-limited current in high-perveance electron guns.
* Heating of an X-ray target by a pulsed beam.
* Periodic permanent-magnet arrays for high-power microwave tubes.
* 3D design of sheet-beam irradiators.
* Shielding of MRI magnets.
* Numerically-exact electron orbits in magnetic or electric deflectors with 3D edge fields.
