摘要：
U-shaped billet (52) has a slot (54) cut therein for receipt of a slip of insulator material (56). This body is machined on its front end (64) to produce a narrow bridge (66) of controlled cross-sectional area. Emitter needle (78) is positioned in a bore through the bridge to be heated by current through the bridge. The ion emitter body is rigid and strong to hold the emitter needle in the proper location.
