DTSA iconDesktop Spectrum Analyzer (DTSA)

Developed by Chuck Fiori, Carol Swyt-Thomas, and Bob Myklebust

A MACINTOSH ONLY! based x-ray spectral analysis and manipulation software package.
The NIST/NIH Desktop Spectrum Analyzer generates, interprets and analyzes x-ray spectra from specimens under electron bombardment. This remarkable software/database package simulates the experimental environment and emulates specimen properties to generate spectra reflecting the relevant physics, chemistry and statistics of a real world application. DTSA incorporates many widely accepted x-ray data analysis procedures including those developed over many years at the National Institute of Standards and Technology (NIST) in Gaithersburg, MD and the National Institutes of Health (NIH) in Bethesda, MD.

This software can be redistributed and/or modified FREELY provided that any derivative works bear some notice that they are derived from it, and any modified versions bear some notice that they have been modified
