ABSTRACT:
Billet (52) of electrically conductive or semi-conductive material has slot (54) therethrough which contains insulator slip (58). In this condition, the ion emitter body (44) is machined with the cylindrical exterior surface (60), conical nose (62) and emitter point (70). The limited electrical path localizes heating under the point (70) and the strong structure of the body permits strong mounting and controlled heat extraction.
