In this paper we present the Chandra X-ray sources detected in the Cetus field, along with an analysis of X-ray source counts, stacked X-ray spectrum, and optical identifications. A total of 188 X-ray sources were detected: 174 in the 0.5-7.0keV band, 154 in the 0.5-2.0keV band, and 113 in the 2.0-7.0keV band. The X-ray source counts were derived and compared with LALA field (172ks exposure). Description: A total of 176ks of Chandra ACIS exposure on the LALA Cetus field was obtained in very faint (VFAINT) mode, composed of two individual observations. The first observation, with 160.4ks exposure, was taken on UT 2002 June 13-14 (Chandra ObsID 4129). The second observation, with 15.4ks exposure, was taken 1 day later (UT 2002 June 15, ObsID 4402).
