Paper Abstract

The feasibility of using low energy (<30 eV) oxygen ions to clean optics has been demonstrated, It was found that the removal rate of a hydrocarbon film is between.10-23 and 10-24 cm /ion. These rates imply that a one meter diameter optic with a 1000 Å layer of organic contaminant can be cleaned with 10 mole (0.32 milligram) of oxygen impinging on the surface. The removal rate varied with the thickness of the film; the lower layers of the film were more difficult to remove than the outer layers. The effect of the ions on the scatter of a gold mirror was also studied. It was determined that the ions increased the scatter by less than a factor of two.
