INTRODUCTION

SIMNRA is a Microsoft Windows program for the simulation of backscattering spectra for ion beam analysis with incident ions from about 100 keV to many MeV. SIMNRA can be used for the simulation of Rutherford backscattering (RBS), elastic backscattering with non-Rutherford cross-sections (EBS), nuclear reaction analysis (NRA), elastic recoil detection analysis (ERDA), and medium energy ion scattering (MEIS). Almost 3000 different non-Rutherford and nuclear reactions cross-sections for incident protons, deuterons, 3He, 4He and Li-ions are included. SIMNRA can calculate any ion-target combination including incident heavy ions and any geometry including transmission geometry. Arbitrary foils in front of the detector and arbitrary beam windows are possible.

The cross-section calculator SigmaCalc by A. Gurbich allows calculating cross-section data for non-Rutherford backscattering and nuclear reactions for many ion-target combinations at any angle: This allows unsurpassed accuracy for the simulation of a large number of elastic backscattering and nuclear reaction analysis measurements.

The capabilities of the program are fully described in the SIMNRA User's Guide (350 pages, PDF, 4547 KB).

SIMNRA is not free. It is a shareware program, which can be used for a trial period of 30 days without fee. If you want to use SIMNRA after this period, you have to register. See Registration / Pricing for registration and pricing details.

SIMNRA is used at more than 220 laboratories world wide and referenced in more than 1400 publications (July 2017). It is the most popular program for the evaluation of ion beam analysis data since 2007, see Citations.

new Current version: SIMNRA 7.01.

SIMNRA was developed by Matej Mayer at the Max-Planck-Institut für Plasmaphysik, Garching, Germany. More information about the author.
