SIMNRA is a Microsoft Windows program for the simulation of backscattering spectra for ion beam analysis with MeV ions. SIMNRA is mainly intended for the simulation of non-Rutherford backscattering, nuclear reactions and elastic recoil detection analysis (ERDA). More than 300 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 and arbitrary foils in front of the detector.

The capabilities of the program are fully described in the SIMNRA User's Guide (220 pages, PDF, 2496 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 130 laboratories world wide, and referenced in almost 700 publications (February 2011). It is the most popular program for the evaluation of ion beam analysis data since 2007, see Citations.

Current version: SIMNRA 6.06, released in February 2011.

SIMNRA was developed at the Max-Planck-Institut für Plasmaphysik, Garching, Germany.
