SZA Goals Take SZ interferometric work to a new level: Purpose built 3.5 m antennas - optimize to cluster (arcminute) angular scales Increase correlation bandwidth to 8 GHz Observe 24 hours x 365 days (from better site) Achieve sufficient sensitivity to blind survey 1 square degree per month Make a catalog of clusters whose mass limit is nearly independent of redshift Add 90 GHz channel for hi-res self follow up
