We report the results of a deep search for faint Chandra X-ray sources, radiosources, and optical counterparts in the nearby, core-collapsed globularcluster, NGC 6752. We combined new and archival Chandra imaging to detect 51X-ray sources (12 of which are new) within the 1.9 arcmin half-light radius.Three radio sources in deep ATCA 5 and 9 GHz radio images match with Chandrasources. We have searched for optical identifications for the expanded Chandrasource list using deep Hubble Space Telescope photometry in B, R, H-alpha, UV,and U. Among the entire sample of 51 Chandra sources, we identify 18cataclysmic variables (CVs), 9 chromospherically active binaries (ABs), 3 redgiants (RGs), 3 galaxies (GLXs), and 6 active galactic nuclei (AGNs). Three ofthe sources are associated with millisecond pulsars (MSPs). As in our previousstudy of NGC 6752, we find that the brightest CVs appear to be more centrallyconcentrated than are the faintest CVs, although the effect is no longerstatistically significant as a consequence of the inclusion in the faint groupof two intermediate brightness CVs. This possible difference in the radialdistributions of the bright and faint CV groups appears to indicate that masssegregation has separated them. We note that photometric incompleteness in thecrowded central region of the cluster may also play a role. Both groups of CVshave an inferred mass above that of the main-sequence turnoff stars. We discussthe implications for the masses of the CV components.
