The missing single-scattering peak in tin ion collisions on Mo and Ru targets

Abstract

Synopsis We report the absence of single-scattering peaks in collisions of tin ions on Mo and Ru targets. For these systems standard simulation packages as e.g. SRIM predict prominent single-scattering peaks. To identify the potential cause of the single-scattering peak missing, we changed charge state, energy, and species of the projectiles, detected ions and neutrals separately and studied collisions of Kr on Cu which has a similar mass ratio of projectie and target particles.

“…may limit the lifetime of the light collecting multilayer optics. Rai et al [100] studied single-collision scattering of keVenergy ions off surfaces to elucidate the absence of a singlescattering peak in the here relevant Sn-Ru collisions [101] and to test the predictive power of standard Monte Carlo binary collision codes such as SRIM (Stopping and Range of Ions in Matter) [102]. These codes, which were primarily developed for modeling swift particle interactions with solid state targets, are also used to simulate the stopping and mitigation of plasma ions in hydrogen buffer gas surrounding the plasma.…”
