Abstract: We present the X-UDS survey, a set of wide and deep Chandra observations of the Subaru-XMM Deep/UKIDSS Ultra Deep Survey (SXDS/UDS) field. The survey consists of 25 observations that cover a total area of 0.33 deg(2). The observations are combined to provide a nominal depth of similar to 600 ks in the central 100 arcmin(2) region of the field that has been imaged with Hubble/WFC3 by the CANDELS survey and similar to 200 ks in the remainder of the field. In this paper, we outline the survey's scientific goals, describe our observing strategy, and detail our data reduction and point source detection algorithms. Our analysis has resulted in a total of 868 band-merged point sources detected with a false-positive Poisson probability of
