More Information
Summary:A collector for use in removing metal ions from a plasma in a vacuum chamber includes a collector plate that is mounted inside the chamber and formed with an internal cooling channel. An injector introduces a dissociated salt into the chamber with a first throughput value, and it introduces a plasma including metal ions into the chamber with a lower second throughput value. A pump is used to pump a liquid coolant through the cooling channel to maintain the collector plate at a temperature that forms a portion of the salt as a protective layer on the collector plate, and causes the salt to thereafter deposit on the layer in a molten condition at a faster rate than evaporation therefrom to trap metal ions therein. The trapped metal ions are then removed with the molten salt from the chamber.
