Xenos软件套件↙是模拟X射线、电子及其相互作用的资源。组件作为耦合或独立应用程序用于电场和磁场计算、电子束设计、辐射传输的蒙特卡罗建模和热分析。
Xenos（X射线/电子数值优化套件）使一组2D/3D有限元程序，可模拟您想了解的有关X射线和电子的全部信息。组件程序计算电场、磁场、带电粒子动力学、材料中的电子-光子-正电子传输和热传输。Professional版在64位Windows机器上具有无限的内存访问和高效的并行处理功能。
下图显示了程序如何作为一个集成系统进行通信。应用程序【几何是在Geometer的交互式图形环境中定义的。MetaMesh使用这些信息为解决方案程序创建六面体元素的保形网格。相同或不同的网格可用于定义1）用于电场计算（HiPhi）的电极和电介质，2）用于■磁场计算（Magnum）的线圈、铁和永磁体，3）用于蒙特卡罗辐射传输的元素和化合物（GamBet）和4）用于热传输的固体材料（HeatWave）。从这一点来看，有几种选择：
GamBet可以从HiPhi和Magnum导入字段信息。在这种情况下，电子和正电子的历史受到洛伦兹力以及物质相互作用的影响。
GamBet可以将信息传输到OmniTrak以跟踪目标（即正电子束）中产生的粒子的轨道
来自HiPhi和Magnum的现场信息可以传输到OmniTrak以设计电子枪和传输系统。然后可以将生成的光束分布发送到GamBet以研究目标相互作用
GamBet记录了沉积功率密度的◆空间发布。HeatWave将这些信息用于静态和动态热模拟

【英文介绍】
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.
