Abstract : The proposed process will use accelerated ions to remove organic matter by physically desorbing molecular fragments and by reacting chemically to produce volatile non-toxic gases such as C02. Work performed 'includes the determination of the optimal size of the process chamber and how surgical instruments can most effectively be arranged in it; the optimal pressure inside the chamber; the required power density; evaluation of alternative power sources and generation of design parameters and a conceptual drawing of the proposed etcher. Feasibility of both cleaning and sterilization are demonstrated in this study.
