We propose an efficient, targeted search for distant clusters of galaxies using bent, double-lobed radio sources as tracers. These types of radio sources have an association rate with clusters of up to 78%, higher than that of either straight-lobed or single-component radio sources. By correlating our radio sample with the SDSS, we have identified host galaxies for objects with z < 0.7. Those sources without hosts detected to the limit of the SDSS are most likely elliptical galaxies in clusters at z > 0.7, and we expect the cluster search will yield approximately 500 clusters beyond this redshift. The sample of clusters found using the radio sources in conjunction with IRAC 3.6 um observations will be used to help determine the epoch of galaxy formation, study the galaxy populations of clusters over time, examine the role that AGN feedback has on clusters as a function of redshift, and (in conjunction with X-ray observations) place constraints on cosmological models, including dark energy.
