	The Structural Characterization [[Beamline Advisory Group\|BAG]] advises the MC group ~~leader~~ and APS management on instruments and infrastructure related to structural determination techniques used at 1-BM, 11-BM and at 1-ID. This work is mostly crystallographic structure determination from powder diffraction, but also covers some micro-PDF work, primarily in diamond-anvil pressure cells and some diffuse scattering work. The membership of this committee can be found on the appropriate [http://www.aps.anl.gov/Xray_Science_Division/xor_committees.html XSD web page].

			As a follow-up to the SC BAG meeting in March, the BAG wrote a report

			This noted with pleasure the performance of the beamline at higher energies (~30 keV) and the
			engineering and operation of the mail-in diffraction service. Priorities for development were
			recommended:
			* publicize and expand the mail-in program
			* purchase a replacement monochromator bender and crystal
			* increase the range of accessible temperatures first below 80K and second above 500 K
			* develop an on-site instrument control interface and then an on-site user program for 11-BM
			* develop a on-site rapid data collection (area detector) program for materials powder diffraction; augmenting the capabilities of 1-BM would be ideal
			* improve energy-change capabilities and extend the usable energy range, but this is of lower priority than the above topics.
