Summary

Space Plasmas at geosynchronous orbit are usually not characterized by a single Maxwellian distribution function. Plasmas are characterized as single Maxwellians to first order and as a sum of two Maxwellians as a better approximation. A threshold electron temperature condition for charging of materials in the single Maxwellian is derived. Conditions for materials charging in the dual Maxwellian case are derived and illustrated. These are threefold: an initial negative current; a threshold electron temperature and a threshold electron current.
