“…Previous work by Coles [1,6] and Miller [7] has investigated the impact of firing voltage, ionic liquid selection, and liquid temperature on the ion beam mass composition and quantified its impacts on propulsive efficiency. Experiments and molecular dynamics simulations have been performed to characterize fragmentation rates of different emitted species as a function of ionic liquid, cluster internal energy, and applied electric field [7][8][9]. N-body simulations that propagate the full ion beam of a single emitter through a realistic electric and potential field have been used to simulate ion beam diagnostics including retarding potential analysis (RPA) curves [10,11], which provide insight on fragmentation events in the sampled beam; most published results sample the beam centerline [12,13].…”
