Institute for Modeling Plasma, Atmospheres, and Cosmic Dust (IMPACT) at the University of
Colorado. This large ion source is being developed for studies of the interaction of solar
wind plasma with planetary surfaces and cosmic dust, and for the investigation of plasma
wake physics. With a plasma beam diameter of 12 cm at the source, ion energies of up to 1
keV, and ion flows of up to 1 mA/cm^ 2, a large cross-section Kaufman Ion Source is used to …
