The ADSC Q315 detector from Area Detector Systems Corporation is a 3 x 3 CCD chip and optic taper detector. The total detector surface is  square of 315 x 315 mm2 with 6144 pixels in each direction, i.e. 51.26 µm pixel size (unbinned mode) for reducing image size the images can been binned dividing by four the total size (3072 pixel squarred for 102.53 µm). There are a total of three cooling systems (next to the bench outside the experimental hutch) and one vacuum pump sitting just next to the detector in the experimental hutch.

The nine CCD are directly connected through nine optic fibers(orange) to nine Windows PC controled by a master Linux PC called adsc231ctrl . These PCs are in the freeway between ID23 and ID22. The Q315R detector is fitted on a dual translation stage (motor called detm and detf) carrying from a minimum distance crystal-detector of 87mm to a maximum of 720 mm. Due to the size of the detector and to avoid detector crashing in the diffractometer, for shorter distance crystal-detector less than 102mm, the detector is translated horizontally by 22 mm (perpendicular to the Xray beam). The beam center is then not aligned with the center of the detector but this change is also transferred to the image header and the input files for further processing.
