“…The microbeam spatial resolution degradation was simulated as a function of exit foil material and beam path length in air by two approaches. The first conventional approach is using SRIM [26] simulation that is known to underestimate degradation of the microbeam spot size [27]. Therefore we have also used a model of small angle multiple scattering being developed by T. Tadić [12,13], on the basis of the most successful theory of small-angle multiple scattering of ions in the screened Coulomb potential, earlier proposed by P. Sigmund and K. B. Winterborn [28], as well as by A. D. Marwick and P. Sigmund [29].…”

One of the possible ways to maintain the micrometer spatial resolution while performing ion beam analysis in the air is to increase the energy of ions. In order to explore capabilities and limitations of this approach, we have tested a range of proton beam energies (2 -6 MeV) using in-air STIM (Scanning Ion Transmission Microscopy) setup. Measurements of the spatial resolution dependence on proton energy have been compared with SRIM simulation and modelling of proton multiple scattering by different approaches. Results were used to select experimental conditions in which 1 micrometer spatial resolution could be obtained.High resolution in-air microbeam could be applied for IBIC (Ion Beam Induced Charge) tests of large detectors used in nuclear and high energy physics that otherwise can not be tested in relatively small microbeam vacuum chambers.

“…It was taken into account that SRIM underestimates lateral straggling for protons up to 45% for Mylar[21] which is assumed to be similar for graphite. This discrepancy still exists in the latest version of SRIM (2003.26).…”

Recently, magnetic order in highly oriented pyrolytic graphite (HOPG) induced by proton broad-and microbeam irradiation was discovered. Theoretical models propose that hydrogen could play a major role in the magnetism mechanism. We analysed the hydrogen distribution of pristine as well as irradiated HOPG samples, which were implanted to µm-sized spots as well as extended areas with various doses of 2.25 MeV protons at the Leipzig microprobe LIPSION. For this we used the sensitive 3D hydrogen microscopy system at the Munich microprobe SNAKE. The background hydrogen level in pristine HOPG is determined to be less than 0.3 at-ppm. About 4.8×10 15 H-atoms/cm 2 are observed in the near-surface region (4 µm depth resolution). The depth profiles of the implants show hydrogen located within a confined peak at the end of range, in agreement with SRIM Monte Carlo simulations, and no evidence of diffusion broadening along the c-axis. At sample with microspots, up to 40 at-% of the implanted hydrogen is not detected, providing support for lateral hydrogen diffusion.
