We propose to study the cosmic acceleration through a precise measurement of the expansion history of the universe (Hubble parameter as a function of redshift) out to redshift z=1. This measurement will result from detailed study of the evolution of the galaxy cluster population over cosmic time using (1) forefront mm-wave instruments to detect galaxy clusters through their Sunyaev-Zel'dovich effect (SZE) and (2) multiband optical data to measure their photometric redshifts. All major mm-wave survey teams that are operating (ACBAR; or soon will operate: APEX, SPT and ACT) in the southern hemisphere have coordinated their mm-wave observing plans, ensuring the maximum scientific return from the proposed MOSAIC imaging. The proposed 100 deg^2 griz survey will push about two magnitudes deeper than SDSS, providing photo- z estimates for galaxies with L≥ L_* at z=1 and L≥ 0.5L_* at lower z. This mm-wave+optical survey will open a unique, large solid angle window on the intermediate to high redshift universe, enabling many other investigations: galaxy based cluster finding, correlations of CMB and optical structure, evolution of galaxy clustering, weak and strong lensing studies and discovery of luminous, high redshift QSO's.
