The design, construction, and operation of GeoSoilEnviroCARS have been funded since 1994 by grants to the University of Chicago from National Science Foundation – Earth Sciences (EAR) and Department of Energy – Geosciences.  The current five-year grants run from 2011-2016.  In addition, a major upgrade of the sector to canted undulator operations was supported (2009-2011) by three agencies (equally divided): NASA-SRLIDAP (now LARS), NSF-EAR-IF (ARRA) and DOE-Single Investigator Small Group (SISGR).  The associated accelerator components (undulators, canted front end) for the upgrade were provided by the Advanced Photon Source using ncomms2160.
