Center for Surface Radiation Damage Studies
Abstract
Research focussed around understanding surface damage processes at the atomistic microstructure level was performed using high resolution electron microscopy in ultra-high vacuum and by other techniques. Techniques for obtaining clean and well-ordered surfaces and understand the image obtained have been developed and used to characterize damage processes. This data, combined with other high resolution electron microscopy data has been combined with analytical and numerical models with a high degree of success. Attempts to produce a small atomic oxygen source based upon electron stimulated desorption of oxygen neutrals led to the conclusion that literature estimates are much too high for the neutral to ion ratio. We have placed a strong upper bound on this ratio of < 10, whereas values in the literature are as high as 10 . Surface Radiation Damage, Electron Microscopy, Electron Stimulated Desorption.
