Title: Optical Follow-up of the XMM Cluster Survey: The XCS-NOAO Survey

Abstract: We propose to image more than 500 X-ray clusters serendipitously detected in XMM-Newton observations. The X-ray cluster candidates are taken from the XMM Cluster Survey (XCS), which will provide thousands of X-ray cluster detections (0<z\lesssim 1.5) over 500 square degrees of the sky. The MOSAIC multi-band ground-based imaging will provide photo- z's and will allow us to estimate X-ray luminosities and temperatures. The combined NOAO and XMM data will allow us to pin down the evolution of the X-ray luminosity-temperature relation and to put useful constraints on \sigma_8, \Omega_matter and \Omega_(Lambda) that are independent to those measured from the CMB or Type Ia supernovae. Simultaneously, the NOAO data will help us understand cluster formation and cluster galaxy evolution through the interplay between the cluster gas and the galaxies over the last 8 billion years. The rapid publication of the unique optical/X-ray dataset produced from the survey will make it possible for the wider community to undertake a broad range of scientific analyses including gravitational lensing and the Sunyaev- Zel'dovich Effect.
