description:
	This will be a collaborative experiment between UOP, NIST (J. Woicik)
	 and UIUC-MRL (A. Frenkel)  to test the performance of the optics on 
	33ID for EXAFS experiments. The experiment will involve performing
	 EXAFS studies:
	 (1) over a wide energy range, e.g. 8-25 keV, (2) using different
	 types of operation of the monochromator e.g. fixed and non-fixed 
	exit mode, and (3) using both focussed and unfocussed beam.  This
	experiment will provide the researchers from all three institutions 
	the experience of operating a DCM from PSL, prior to the final 
	design review of the DCM for 33BM.  We will study well-defined 
	systems e.g metal foils and samples where data has been collected 
	at other facilities.  Now that the stability issues of the DCM have 
	been addressed and harmonic rejection mirrors have been installed 
	we feel this will be a true test of 33ID. 

equipment+required:
	Ion chambers and associated electronics, XZ stage

experiment:
	EXAFS studies using ID beam

hazards:
	There are no hazards associated with the experiment.  Data will be
	collected at room temperature on stable materials, e.g metal foils,
	and on catalysts e.g. Pt on alumina
