GSECARS Update13-BM-C Side Station

•Scientific programs is DAC diffraction and surface science

•Proposed partial funding as COMPRES Infrastructure Project. COMPRES could not fund, recommended submission to NSF-MRI

•Funded by MRI for $550K ($100K less than requested).

•Monochromator prototype being constructed•Will order vertical mirror soon•Large Newport diffractometer will be

delivered in July, DOE funded.
