The Smithsonian's Astronomy At The South Pole provides information related to the CARA work in sub millimeter wavelength observations. Initial results and descriptions of core are already published. The figure is of the LHC and Lepton Machine. Support for this project will be provided by several European countries and the U.S. NSF and the DOE would contribute to the construction of two detectors for this facility. Participants are from all of Latin America and the Caribbean Basin.
Primary participants are from North America, Western and Eastern Europe, including Russia.
All NSF-supported research facilities in the United States are open to visiting scientists and students from other countries. Some facilities, however, are explicitly committed to international service, often having institutional agreements and arrangements with partner institutions in other countries. It maintains close ties with similar centers in Europe and Japan. For more details, see Progress on the Construction Sites. These facilities maintain an open door policy, without user fees, and provide access to their instruments on a competitive basis, giving priority to U.S. researchers.
