Introduction

• NISTMonte is a Monte Carlo simulation of electron and x-ray transport in solid materials.

Major features:

• NISTMonte simulates the trajectory of energetic electrons as they interact with matter.
• NISTMonte models characteristic x-ray generation as a result of electron-induced inner shell ionization
• NISTMonte models Bremsstrahlung x-ray generation resulting from electron deceleration
• NISTMonte models complex sample geometries including those build from cylinders, blocks, spheres and the intersection of multiple planes
• • Most samples can be arbitrarily rotated and translated in 3-space
• NISTMonte provides a mechanism for attaching multiple simultaneous x-ray and electron detectors to facilitate dynamically recording various electron and x-ray measurables.
• • Available electron detectors include a backscatter/forward scattered electron detector, an annular detector, an electron trajectory image and an interactive 3-D trajectory virtual reality markup language (VRML) world.
  • Available x-ray detectors include a detector emulating an EDS detector, x-ray emission images
  • NISTMonte provides a mechanism to add new detectors without modifying existing code.
• NISTMonte provides multiple different interchangeable physical models
• • Elastic cross section – Three alternatives
  • Inelastic cross section – One alternative
  • Ionization cross section – Three alternatives
  • X-ray mass absorption coefficients – Eleven alternatives
  • Fluorescence yield – Three alternatives
  • Electron energy loss – One alternative
  • Additional user implemented models can be readily integrated
• NISTMonte is available as Java source code with JavaDoc API documentation
• • Pursuant to title 17 Section 105 of the United States Code NISTMonte is not subject to copyright protection and is in the public domain
• NISTMonte algorithms are designed in a library format to facilitate integration into other applications.
• NISTMonte can be scripted using Jython to facilitate the design of complex simulations
• NISTMonte is available with source code
• NISTMonte can run on many different platforms (Microsoft Windows, GNU/Linux, Sun Solaris, Apple OS-X)
