We propose a program to image the first sample of galaxy clusters selected at mm-wavelengths via the Sunyaev-Zeldovich Effect (SZE). We have chosen a sample of 84 robust, high-significance clusters (S/N >D 4.5) from the first 350 deg^2 of the ongoing > 1000 deg^2 South Pole Telescope (SPT) SZE survey. These clusters are selected on total mass, independently of redshift, and as such form the ideal sample for studies of massive galaxies in rich environments over a wide range of redshifts. The IRAC data will provide photometric redshifts and stellar mass estimates for both field galaxies and cluster members, allowing studies of the cluster IR luminosity and stellar mass function evolution over the last 10 Gyr in a unique, unbiased cluster sample. Finally, in concert with our ongoing, extensive multiwavelength and spectroscopic follow-up programs, the proposed data will allow empirical calibration of the relationship between SZE, X-ray, IR and dynamical measures of cluster mass, which will ultimately allow accurate constraints to be placed on the equation of state of dark energy.
