Small Vacuum Compatible Hyperthermal Atom Generator

A vacuum compatible hyperthermal atom generator includes a membrane having two sides. the membrane having the capability of dissolving atoms into the membrane's bulk. A first housing is furnished in operative association with the first side of the membrane to provide for the exposure of the first side of the membrane to a gas species. A second housing is furnished in operative association with the second side of the membrane to provide a vacuum environment having a pressure of less than 1 x 10(exp -3) Torr on the second side of the membrane. Exciting means excites atoms adsorbed on the second side of the membrane to a non-binding state so that a portion from 0% to 100% of atoms adsorbed on the second side of is the membrane are released from the second side of the membrane primarily as an atom beam.
