Limitations of Using BCA Codes for Modeling the Sputtering Behavior of Planetary Surfaces
Noah Jäggi, Adam Woodson, Paul Szabo +3
Binary collision approximation (BCA) codes are potentially powerful tools to simulate ion irradiation ejecta properties, such as the composition and the angular and energy distribu…
Sputter Yields of the Lunar Surface: Experimental Validation and Numerical Modelling of Solar Wind Sputtering of Apollo 16 Soils
Johannes Brötzner, Herbert Biber, Paul Stefan Szabo +12
Sputtering by solar wind ions is a key process driving the ejection of high-energy particles into the exospheres of airless bodies like asteroids, Mercury and the Moon. In view of…
Solar-Energetic-Particle Track-Production Rates at 1 au: Comparing In-situ Particle Fluxes with Lunar Sample-Derived Track Densities
A. R. Poppe, P. S. Szabo, E. R. Imata +2
Heavy (Z>26) solar energetic particles (SEPs) with energies ~1 MeV/nucleon are known to leave visible damage tracks in meteoritic materials. The density of such solar flare tracks…
Towards quantitative Low Energy Ion Scattering on CaSiO from Comparison to Multiple-Scattering-Resolved Dynamical Binary Collision Approximation Simulations
Johannes Brötzner, Matthias Kogler, Paul S. Szabo +6
We perform Low Energy Ion Scattering with He ions ranging in energy from 1 keV to 3 keV on CaSiO using a commercial electrostatic detector system and determine the charge fract…
