The SPT‐SZ is, currently, the most powerful instrument for detecting galaxy clusters through the Sunyaev‐Zel’dovich (SZ) effect. The SPT‐SZ focal plane consists of over 700 background limited TES spiderweb bolometers observing in three different pass bands (90 GHz, 150 GHz, and 220 GHz) readout by a frequency domain SQUID multiplexer. Together with the 10‐m South Pole Telescope, SPT‐SZ has realized exceptional sensitivity at arcminute resolution over a one degree field of view and is the first instrument to discover new galaxy clusters through the SZ effect. We will discuss the SPT‐SZ design and deployment, present initial results from the first two seasons, and outline future survey plans.
