A multiple-CCD X-ray detector and its basic characterization

The Station Equipment Group of JASRI and the SR Structural Biology Research Group of RIKEN have designed and constructed a 4 × 4 array of CCD X-ray detectors called the `multiple charge-coupled-device X-ray detector (MCCDX)' in collaboration with EEV in the UK. The novel features of the system are the lower demagnification factor of its fibre-optics taper assembly and the higher operational temperature, when compared with similar detector systems already in existence. The present paper describes the design concepts of the MCCDX system as well as the basic characterization of the constructed MCCDX system, which was carried out by using a conventional X-ray generator system prior to its installation on RIKEN beamline I (BL45XU) of the SPring-8 facility.
