This component provides user support at the Earth science beamlines at synchrotron and neutron facilities. At present, these include all of the high-pressure beamlines at NSLS and at ALS, as well as coordination with GSECARS at the APS. Other beamlines may fall under this heading as well. The current subprojects and lead scientists include:
· Multi-anvil High Pressure Facilities at National Synchrotron Light Source
Operated by Stony Brook University [D.J. Weidner and M.T. Vaughan]
· West-Coast Synchrotron Facilities at Advanced Light Source
Operated by University of California Berkeley [R. Jeanloz and S. Clark]
· Infrared Diamond-Anvil Facilities at National Synchrotron Light Source
Operated by Carnegie Institution of Washington [Z. Liu and R.J. Hemley ]
· X-ray Diamond-Anvil, Facilities at the National Synchrotron Light Source
Operated by Princeton University [T. S. Duffy] and Stony Brook University [D. J. Weidner]
· Neutron Studies at National Facilities
Operated by Virginia Polytechnic Institute and State University [N.L. Ross]
A Standing Committee oversees the Community Facility Program. This committee will evaluate the effectiveness of the service delivered by the community facilities. The Committee will coordinate between facilities (such as between beamlines) so as to maximize the community’s effectiveness in using these facilities. This Committee will consider the community’s needs and recommend changes in the levels of support of all possible community facilities.
This component works with the COMPRES community to identify critical technological needs of the community. Our tools, including both beamlines used by Earth scientists and equipment used in our home laboratories, need to be continually developed to improve the science that they support.
