The DEEP2 Survey (ref) fields are being observed with Chandra. Fields 2 and 4 were observed with a mosaic of 12 and 11 ACIS pointings with exposure times of 7 to 9 ksec per pointing, and Field (Extended Groth Strip; EGS) has been observed for about 200 ksec per pointing.Field 3 is scheduled to be observed in August 2008. For Fields 2 and 4 we have analyzed the data in a manner similar to that for the Xbootes Shallow Survey (Murray et al. 2005) and detect about 550 sources per field (each DEEP2 field is about 1/2 square degree in total area) to a flux limit of 3 counts/9 ksec which corresponds to about 3x10-15 erg/cm2/sec. We have matched the X-ray sources against the DEEP2 photometric catalog and also the redshift catalog. About 25% of the X-ray sources have a counterpart in the redshift catalog (most are galaxies with redshifts between 0.7 and 1.4, as expected) and about 67% of the X-ray sources have a\ counterpart in the photometric catalog. We examine the redshift distributions and the R magnitude distributions of the X-ray sources and compare with the XBootes Shallow Survey results. For the EGS, the exposure times are much longer and the corresponding flux limit is about 8 x 10-16 erg/cm2/sec. For EGS we use the IRAC and X-ray data to study the average X-ray properties (e.g., luminosity and spectrum) of selected sub-samples.
