ABSTRACT:
The emitter includes hollow cylindrical cathode, which has a multi-apertured emission window at one end, and a coaxial rod-shaped anode at the other end, mounted with a feed-through insulator. A magnetic coil is mounted coaxially on the outside of the cathode and creates a magnetic field. The cathode has an internal open chamber or space filled with a gas and with the applying of a voltage between the cathode and anode the gas discharge starts. The ions are extracted from the gas discharge plasma through the emission window.
