Abstract:
A method and apparatus for treating material smfaces (13) using a repetitively pulsed ion beam (11). In particular, the treatment is tailored by adjusting treatment parameters of a pulsed iorl beam (11) to a duration less than or equal to 1000 ns and a repetition rate of less than 1 Hz.
Abstract:
A polymer surface and near surface treatment process produced by irradiation with high energy particle beams. The process is preferably implemented with pulsed ion beams. The process alters the chemical and mechanical properties of the polymer surface in a manner useful for a wide range of commercial applications.

Abstract:
The present invention is for a high-speed, commercial-scale means for deposition of films and coatings on a substrate. The PIBAD (pulsed ion beam assisted deposition) processes [Fig. 4] allow notonly deposition, but also special modes of post-deposition treatment of films and coatings, including annealing, melting and regrowth [Fig. 4A], shock wave treatment, and high-pressure plasma redeposition [Fig. 4B] all of which can alter the mechanical, cohesive, and corrosive properties of the final product. In one embodiment of the invention the power system comprises a motor (5) which drives an alternator (10). The alternator delivers a signal to a pulse compression system (15) which has two subsystems, a 1 mu s pulse compressor (12), and a pulse forming line (14). The pulse compression system (15) provides pulses to a linear inductive voltage adder (LIVA)(20) which delivers the pulses to the ion beam source (25).

Abstract:
Methods and apparatus for thermally altering the near surface characteristics of a material are described. In particular, a repetitively pulsed ion beam system comprising a high energy pulsed power source and an ion beam generator are described which are capable of producing single species high voltage ion beams (0.25-2.5 MeV) at 1-1000 kW average power and over extended operating cycles (108). Irradiating materials with such high energy, repetitively pulsed ion beams can yield surface treatments including localized high temperature anneals to melting, both followed by rapid thermal quenching to ambient temperatures to achieve both novel and heretofore commercially unachievable physical characteristics in a near surface layer of material.
