摘要
Possible mechanisms for the charging and entrapment of particulate contamination in a cylindrical ion beam are investigated. A model is developed which describes the charging, and steady-state charge acquired by the particle. Confinement within the beam is then investigated by comparing the resulting electric force with the opposing force of gravity. The model predicts a region about the center of the beam where a net trapping force may exist. Calculations of this force for various operating conditions suggest a strong dependence on parameters that affect the beam-ion density.
