Compres

COMPRES provides user support and technological development at the high-pressure beamlines of the National Synchrotron Light Source [NSLS] of the Brookhaven National Laboratory and the Advanced Light Source [ALS] of the Lawrence Berkeley National Laboratory.

COMPRES also coordinates with the high-pressure beamlines at the Advanced Photon Source [APS] of the Argonne National Laboratory [operated by GSECARS] and the Spallation Neutron Source [SNS] of the Oak Ridge National Laboratory [operated by SNAP-Spallation Neutrons at Pressure].

· Community Facilities

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]
Multi-anvil high-pressure facility at X17B2 (NSLS page)

· West-Coast Synchrotron Facilities at Advanced Light Source
Operated by University of California Berkeley [R. Jeanloz and S. Clark]

    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.
