WebThe trajectories of ions and energetic neutrals (resulting by ion neutralization on surfaces or charge exchange collisions in the gas phase) were then followed with a MC simulation. In this paper, ion flow, energy and angular distributions of ions, and energetic neutrals bombarding an otherwise planar surface with a step are reported. WebSecondary ion yields and secondary ion energy distributions were examined as a function of the primary ion energies from 50 eV to 100 eV, and as a function of the primary ion mass using He, Ne, and Ar. Emphasis has been placed on characterizing the instrumental operating and response.
