We present X-ray results from Chandra observations of the Bootes 9 square degree survey field. This field corresponds to the northern half of the National Optical Astronomy Observatory (NOAO) Deep Wide Field Survey (NDWFS).

In March 2003, the Chandra X-ray Observatory (CXO) completed 126 ACIS-I observations each of approximately 5ksec seconds in duration. These observations were centered on right ascension \alphaJ2000 \approx 14hr32min and declination \deltaJ2000 \approx 34\deg06min and were arranged in a mosaic with a total field of view of ~9.3 square degrees. This unique set of observations allows the calculation of X-ray source statistics over a wide, contiguous field of view with unprecedented angular resolution and uniform coverage.

In our full band (0.5-7keV) sample we detect ~3000 point and ~40 extended sources. Limiting the point source list to sources with \ge 4 counts, and assuming a simple AGN-type power law spectrum, these observations reach a flux of ~4 \times 10-15~ergs~cm-2~s-1 in the 0.5-2~keV band, ~2 \times 10-14~ergs~cm-2~s-1 in the 2-10keV band and ~8 \times 10-15~ergs~cm-2~s-1 in the 5-10keV band.

We present the number of sources per flux density interval (N(S)). We present hardness ratios and we examine the distribution of X-ray sources for evidence of large scale structure. We discuss our analysis techniques and related Monte Carlo simulations. Funding for this research was provided in part by NASA contracts NAS8-38248, NAS8-01130,NAS8-39073 and GO grant GO3-4176A.
