The Chandra Multiwavelength Project (ChaMP) aims to amass and characterize a deep, wide-area sample of serendipitous X-ray sources detected by the Chandra X-ray Observatory, for studies of the nature, evolution, and clustering of X-ray selected AGN and galaxies. Chandra's broadband X-ray sensitivity (0.3-8keV) means that our sample is far less affected by absorption than previous optical, UV, or soft X-ray surveys, and unlike radio surveys will allow the first complete census of the intrinsic population of AGN (not just the radio bright fraction). Chandra's unique, ≲ 1 arcsec astrometry and low background enables unambiguous identification of optical counterparts to X-ray sources 10- 20 times fainter than any X-ray observatory past or present. We propose here a continuation of our program of optical imaging and spectroscopy of the ChaMP sample, to provide the first estimate of the intrinsic luminosity function of AGN and its evolution, and thereby to constrain the history of accretion power in the universe. The ChaMP survey products will enable a wide range of follow-up science, from studies of stellar coronal emission, to cluster evolution and cosmology.
