South Pole Telescope

(a microwave to radio telescope at South Pole)

The South Pole Telescope (SPT) is a 10 meter Microwave and millimeter telescope at the South Pole aimed at discovering more detail about the Cosmic Microwave Background (CMB). Part of the location's advantage is its altitude: 2800 meters or 9300 feet. Instruments include:

  • SPT-SZ camera - a Bolometer array (95 GHz, 150 GHz, and 220 GHz)
  • SPTpol camera - detects Polarization (90GHz and 150 GHz)

The telescope went into service in March 2007.

These Frequencies are useful for finding distant Galaxy Clusters (CL).
