The South Pole Telescope (SPT) is a 10-meter telescope operating at the National Science Foundation's 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. Currently, the third generation "SPT-3G" camera is surveying the southern sky to make an ultra-sensitive map of CMB polarization across 1500 sq. degrees, and construct an unprecedented catalog of high redshift galaxy clusters. This latest camera upgrade has more than 10 times more detectors than its second-generation predecessor, SPTpol.
