Soft x-ray microscopy at Stony Brook

Abstract
Recent activities in soft x-ray microscopy by the Stony Brook group at Brookhaven lab are described. In collaboration with Lucent Technologies Bell Labs, we have fabricated zone plates in nickel with outer zone widths as small as 20 nm. We have begun to operate a cryo microscope which is able to image frozen hydrated biological specimens; this has yielded surprising results on radiation sensitivity and on preparation methods. Applications of x-ray microscopy for cell labeling, for cell science, and for exobiology (including the mars meteorite) will also be discussed.
