DOWNLOAD CURRENT VERSION OF SIMNRA 7.0
Current version: SIMNRA 7.04, May 2025
SIMNRA is a Windows 7/8/10/11 program for the computer simulation of ion beam analysis methods using MeV ions.
SIMNRA can be downloaded with the cross-section calculator SigmaCalc (recommended), or without SigmaCalc. SigmaCalc has been developed by A. Gurbich and allows calculating cross-section data for non-Rutherford scattering and nuclear reactions. See the SigmaCalc page for more information. See Pricing for information about the price of SigmaCalc.
By installation of SIMNRA you agree to the product license agreement.

Main changes
- Expert system for checking the simulation parameters.
- Considerably faster calculation of straggling (electronic energy loss straggling and straggling due to porosity). Overall speed improvement typically in the range 10 - 40%.
- Faster calculation of stopping powers and derived quantities, such as energy loss and straggling. Overall speed improvement typically in the range 10 - 20%.
- Modern display of isotope and reaction names with isotope masses in superscript and number of excited state in subscript.
- Up to 100 spectra of elements and isotopes are displayed.
- Various bug fixes if multiple instances of SIMNRA are running simultaneously.
- Improved reading of Fast MPA files.
- If the file name contained dots (such as 'Measurement.170deg'), then the last part was erroneously interpreted as file extension and replaced by 'xnra'. Bug fixed.
- Various other bug fixes.
- See the file Changes.txt for a full list of changes.
