Measurements and modelling of solid phase lithium sputtering

摘要: The absolute sputtering yields of D+, He+ and Li+ on deuterium saturated solid lithium have been measured modelled at 45° incidence in the energy range 100-1000 eV. Ion-surface InterAction Experiment (IIAX) was used to measure yield phase from bombardment with a Colutron ion source. sample treated plasma hollow cathode Measurements also include non-deuterium-saturated surfaces. results lead conclusion that chemical state surface plays major role decrease yield. Specifically, preferential implanted atoms over samples least 60% yield, case bombardment. These demonstrate self-sputtering is well below unity fraction sputtered species an ionic ranges 55 65% for incident particle energies between 100 1000 Furthermore, correlation Monte Carlo VFTRIM-3D simulations IIAX experimental data composition has one ratio components.
