Overview:

The mass production anode layer ion source was originally developed as an ion source for the Mark 3 fusor, allowing neutron production rates up to 2.4e6n/s (as of fall 2016) and significant improvements in operation stability. The mass production version uses SmCo magnets instead of NdFeB magnets to allow high temperature(~300C) operation / bakeout and use in a hydrogen/deuterium environment without hydrogen embrittlement; NdFeB magnets will disintegrate after absorption of enough hydrogen. The Pole piece and case are CNC machined for closer tolerances and better reproducibility.

An anode layer ion source consists of a positively biased ring shaped anode between two grounded magnetic poles that create a radial magnetic field across the anode ring. Electrons drift above the ring due to the ExB force and ionize gas (either ambient or a controlled flow over the anode ring) which is then directed into a ring shaped beam. Anode layer sources have been used as satellite thrusters, plasma sources, for thin film deposition or surface treatment.

The ion sources are for sale see Techplasmas website.
