NIST DTSA-II is software for quantifying and simulating electron probe microanalysis spectra.
DTSA-II is inspired by the original DTSA developed by Fiori, Mykelbust and Swyte. While the original DTSA is only available for the old Mac OS 8 & 9, DTSA-II is available for OS X, Linux, Windows and any other OS with Java 1.6 support. Full source code is available.
Lispix, and its predecessor are freeware image analysis
packages written in Lisp by Dave Bright at NIST.
Features of Lispix include RGB color overlays, real image arithmetic, two dimensional histograms, averaged scan lines, data cubes, image registration, stereo movies, linear Hough transform, FFT, simultaneous zoom and scroll with navigator, measurements and statistics on groups of images.
LFPF is software for estimating the position, width and asymmetry of the interface between dissimilar materials
LFPF is written by William H. Kirchhoff. The Logistic Function Profile Fitting program is based on a Fortran program written for DOS and originally issued under the name LOGIT. This program was successfully used to fit Auger sputter-depth-profile data [W. H. Kirchhoff, G. P. Chambers, and J. Fine, J. Vac. Sci. Tech. A 4, 1666 (1986)]. This approach and the associated software were applied in a number of laboratories, and formed the basis for an ASTM standard [E 1636-04: Standard Practice for Analytically Describing Sputter-Depth-Profile Data by an Extended Logistic Function]. The logistic function (although not the specific LOGIT or LFPF software) has also been used to describe Auger linescans [S. A. Wight and C. J. Powell, J. Vac. Sci. Tech. A 24, 1024 (2006)].
NISTMonte is a platform for modeling electron and x-ray transport
The functionality in NISTMonte has been subsumed into DTSA-II. New users are suggested to use DTSA-II for electron and x-ray transport simulation.
NISTMonte is a full-featured Monte Carlo simulation of electron and x-ray transport in complex 3D sample geometries. NISTMonte provides a flexible script-based interface which permits complex multi-material sample geometries and multiple detection schemes including spectrum generation. NISTMonte is written in Java and can run on Windows, Linux, Solaris, Apple OSX and any other Java 5 supported platform. Source code is provided.
CITZAF GUI is a simple, user-friendly program for performing x-ray microanalysis corrections for Windows platforms
Developed at NIST by Daniel Davis, the CITZAF GUI is a significant step forward for running ZAF corrections. Based off of the CITZAF developed by Dr. John T. Armstrong, this program provides a slew of corrections methods and other customizations for easy and accurate analysis of data.
