摘要:

A thermionic source of singly charged alkali ions consisting of an aluminosilicate‐molybdenum emitter assembly rigidly mounted behind a Pierce‐type electrostatic focusing structure is described. This ion source is compatible with an ultra‐high vacuum environment and has generated intense, high purity ion beams for a continuous operating period of one month.
