description:
	A proper desmearing of standard USAXS 
	is fundamental to routine data reduction.
	Recent experiments by the Zukoski group
	at UIUC indicate problems in desmearing
	USAXS data from colloidal silica spheres
	in glycerine suspensions.
	
	We propose to measure the USAXS from 
	colloidal silica spheres in glycerine
	with standard instrument geometry and
	with side-bounce geometry.  We will thus
	have comparison datasets to evaluate
	our desmearing procedures.

	Where do I tell you that Jan Ilavsky is also part of this work?

unacceptable+dates:
	Since we will use both USAXS geometries in this experiment,
	and it requires some time to set up the side-bounce, it would
	be preferable to schedule this experiment at the end of a 
	USAXS side-bounce run.  A second choice would be between 
	standard and side-bounce experiments.
	
	Note that side-bounce geometry takes about 8 hours of setup time
	starting from a standard USAXS configuration.
