The South Pole Telescope (SPT) is a 10-m, off-asix Gregorian telescope equipped with a ~1k-pixel, 3-colour, millimetre-wave bolometer camera. The telescope has an unblocked aperture, shielded beams and co-moving ground shields to minimize systematic errors due to scattering. SPT has just started a large survey of galaxy clusters using the Sunyaev-Zel’dovich effect. The goal is to set constraints on dark energy by measuring the redshift evolution of the density of clusters.
