description:
	This is a request based on GUP 6708 by Xiao et al., which received a rating of 1.9.

We plan to apply our newly developed crystal aperture technique to guard unwanted scattering background in coherent diffraction imaging of single particle objects.  Specimens to be tested will include multi-twinned electrodeposited Pb microparticles, and freeze-dried yeast cells.

Preliminary experiments have already been performed at 32-ID but a direct detection CCD was not available.  A direct detection CCD is required to achieve the highest resolution needed for useful interpretations of the data.
