Abstract	MEIS program developments in the past year have been dominated by the successful commissioning of and software development for the BER-ERSD-funded hard x-ray microprobe at beam line 2-3, which allows for chemical imaging and XAS characterization of samples with 2 µm resolution. Developments will continue apace this year with the planned commissioning of a new x-ray CCD detector which will provide the capability to perform µ–XRD measurements, and a monolithic 3-element Ge detector, which will significantly improve photon collection. Planned upgrades at BL 11-2 include the development of in-situ and cryogenic sample cells for GI-XAS measurements and implementation of pitch feedback to stabilize beam motion in focused mode. The MEIS group will lead the effort to instrument and commission the BL 4-1 XAS experimental, due to start in the next year.
