Scientific paper

We propose a deep initial study of the CV population and dim x-ray sources in two globular clusters, NGC 6397 and 47 Tuc. Both clusters have extensive dim (Lx ~ 10^31-33 erg/s) x-ray source populations which our ROSAT/HST studies have shown are likely dominated by CVs although the brightest sources in 47 Tuc may also include quiescent LMXBs. The HRC-I (47Tuc) and ACIS-S (NGC 6397) images will allow the luminosity function, variability, and source identifications (with planned HST followup) to be measured and constraints on the origin of cluster WDs and NSs as well as compact binaries in these two contrasting globulars (differing in metallicity, halo vs. disk, and mass) to be derived. A complementary ACIS-S study of 47Tuc will measure spectra of both dim sources and the diffuse emission.
