ABSTRACT:
An ion projection head designed to provide a fairly uniform cloud of ions over a wide area for use in therapeutic and industrial applications, among others. The head, although being relatively small, generates a large ion cloud in a very efficient manner. A point electrode is located in a cup having a spherical internal surface of curvature. This cup causes the ions to move in a relatively common direction. An iris plate over the mouth of the cup causes the ions generated in the cup to be propelled away from the iris plate.
