The 3rd Suzaku international Conference "Energetic Cosmos : from Suzaku to ASTRO-H" (June 29-July 2, 2009. Grand Park Otaru Hotel), Otaru, Hokkaido Japan

The Swift-XRT Deep Serendipitous Survey is a large ( approximately 32.5 deg.(sup 2)) rather deep ( 0.5 - 2 keV flux limit approximately 7 x 10(sup -16) erg cm(sup -2) s(sup -1)) X-ray survey obtained by searching for serendipitous sources around 372 Gamma Ray Burst (GRB) observed with the XRT telescope on board of the Swift satellite, from January 2005 to December 2008. Here, we report on the strategy, design and execution of the survey, and we present first results on the catalog of point-like X-ray sources detected in the observations carried out between January 2005 to June 2007 (237 fields). For the high Galactic latitude fields (i.e. absolute value of b > = 20 deg.), we also present the X-ray number counts (i.e. LogN-LogS), that is consistent with previous results.
