NISTMonte

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

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

MKL : Intel Math Kernel Library

® Intel Math Kernel (MKL)

La Librairie Math Kernel (MKL) pour une architecture Itanium II prend en compte les routines suivantes :

- BLAS (Basic Linear Algebra Subprograms) : Level 1,2 et 3
- LAPACK : toutes les routines LAPACK version 3
- Sparse Solver(Solveur Creux) : Routines pour la résolution de Systèmes linéaires creux
- Vector Math Library (VML) : Permet des opérations de type tan, sqrt,exp, sur des vecteurs
- Vector Statistical Library (VSL) : Génération de nombre aléatoires
- FFT : Deux interfaces sont fournies pour les transformées de Fourier Rapides : L’interface recommandée est DFT (Discret Fourier Transform) en Fortran90 qui fournie assez de fonctionnalités et de fléxibilité pour couvrir la plupart des besoins FFT.
