Abstract: A method and apparatus for treating material surfaces (13) using a repetitively pulsed ion beam (11). In particular, the treatment is tailored by adjusting treatment parameters of a pulsed ion beam (11) to a duration less than or equal to 1000 ns and a repetition rate of less than 1 Hz.

Abstract: An improved magnetically-confined anode plasma pulsed ion beam source (25). Beam rotation effects and power efficiency are improved by a magnetic design which places the separatrix between the fast field flux structure (408) and the slow field structure (414) near the anode (410) of the ion beam source, by a gas port design (404, 406) which localizes the gas delivery into the gap between the fast coil (408) and the anode (410), by a pre-ionizer ringing circuit connected to the fast coil, and by a bias field means (180) which optimally adjusts the plasma formation position in the ion beam source.
