South Pole Telescope (SPT)

The South Pole Telescope (SPT) is a 10 meter diameter telescope operating at the NSF South Pole research station. Designed for conducting large-area millimeter and sub-millimeter wave surveys to map primary and secondary anisotropies in the cosmic microwave background, SPT is the largest telescope ever deployed at the South Pole. As on February 2018, the SPT team is working to bring the 3rd generation `SPT-3G' camera up to full sensitivity. The upgraded camera will have more than 10x more detectors than its 2nd generation predecessor, SPTpol, and will be used to make an ultra-sensitive map of CMB polarization across 1500 sq. degrees, and construct an unprecedented catalog of high redshift galaxy clusters.
