The Chandra Archival Survey of Galaxy Clusters project is a wide-area(~40 deg2) survey of serendipitous Chandra X-ray sources in galaxy cluster fields, containing ~58,000 X-ray point sources in ~800 Chandra ACIS observations of ~600 galaxy clusters. It covers an intermediate flux range of fx=10-15 –10-13 erg sec-1 cm-2 in the 0.3-8 keV. We found ~800 extended source in our sample. The aim of this project is to compare physical properties of X-ray point sources in galaxy cluster fields to those in blank fields such as the Chandra Deep Fields (CDFs: e.g. Brandt et al. 2001, AJ, 122, 2810; Alexander et al. 2003, AJ, 126, 539) and the Chandra Multiwavelength Project (ChaMP: Kim, D. et al. 2004, ApJS, 150, 19; Kim, M. et al. 2007, ApJS, 169, 401) fields for investigating the density environmental effects on the physical properties of X-ray sources. We present the source counts, flux, hardness ratio, and X-ray colors of the X-ray point sources of this project. Using this catalog, we derive the radial surface density profiles of the X-ray point sources in galaxy clusters. We performed extensive Monte-Carlo simulations to utilize the X-ray point source catalog. In this presentation, we show the the detection probability of the X-ray point sources in galaxy cluster fields and those in typical fields.
