Abstract
A plasma source is used which provides a high flux output. It is based on a gaseous discharge in a UHF magnetic field. The particle velocity is relatively low to allow interactions within a reduced length. The plasma (4) generated is accelerated as a 'sheet' by the magnetic field established by a propagating series of slot electrodes (31). The slot spacing is slightly less than the critical value required to prevent the plasma from entering the structure. The field is injected into the slot structure (31) at one side via a tapered waveguide (2) and sealing window (20). The source gas enters from a central channel (5) opening into the slot volume.
