In this study, we examine the scattering of inert-gas ions from Al(1 1 1) using low energy ion scattering (LEIS). These techniques, because of their high surface specificity, provide structural and compositional information from the first atomic laye

Erosion of the main chamber plasma-facing components is of concern for ITER. Plasma interaction with the outboard chamber wall is studied in DIII-D using Langmuir probes and optical diagnostics. Fast camera data shows that edge localized modes (ELMs)

Ion scattering spectroscopy (ISS) is often used to identify the masses of surface atoms through measurement of scattered-ion energies. Mass analysis is straightforward when the scattering events can be described by binary elastic collision kinematics

The location of deuterium adsorbed on W(1 0 0) has been studied using a combination of angle-resolved low-energy ion scattering (LEIS) and direct recoil spectroscopy (DRS). These techniques provide real-space data on both substrate and adsorbate surf
