The Xenos software suite is the ultimate resource to model X-rays, electrons and their interactions. Components function as coupled or stand-alone applications for electric and magnetic field calculations, electron beam design, Monte Carlo modeling of radiation transport and thermal analysis.

?

Xenos (X-ray/electron numerical optimization suite) is a set of advanced 2D/3D finite-element programs that simulates everything you'll want to know about X-rays and electrons. Component programs calculate electric fields, magnetic fields, charged-particle dynamics, electron-photon-positron transport in materials and thermal transport. The Professional version features unlimited memory access and efficient parallel processing on 64-bit Windows machines.

The application 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.
