QUIET was an astronomy experiment to study the polarization of the cosmic microwave background radiation.[1] QUIET stands for Q/U Imaging ExperimenT. The Q/U in the name refers to the ability of the telescope to measure the Q and U Stokes parameters simultaneously. QUIET was located at an elevation of 5,080 metres (16,700 feet) at Llano de Chajnantor Observatory in the Chilean Andes.[2] It began observing in late 2008 and finished observing in December 2010.[3]

QUIET was the result of an international collaboration that had its origins in the CAPMAP, Cosmic Background Imager (CBI) and QUaD collaborations. The collaboration consisted of 7 groups in the United States (the California Institute of Technology, the University of Chicago, Columbia University, the Jet Propulsion Laboratory, the University of Miami, Princeton University and Stanford University), 4 groups in Europe (the University of Manchester, the Max-Planck-Institut für Radioastronomie Bonn, the University of Oslo and the University of Oxford) and one group in Japan (KEK; the first time a Japan group has been involved in CMB studies). Other members of the collaboration are from the University of California, Berkeley, the Goddard Space Flight Center and the Center for Astrophysics | Harvard & Smithsonian.[1]
