description:
	Last run we measured weak but distinct CXD patterns from InAs/GaAs quantum dots.  This gives us confidence the method will work for Ge dots.  David Cahill (UIUC) has grown some randomly distributed arrays in the 50nm size range.  This means that there will be fewer than 100 in the focussed beam, which should give a clear diffraction pattern.  Because of the overlap of the GeSi and Si peaks (not a problem for InAs/GaAs), resonant scattering (Ge K edge 11keV) will be helpful.
