COUPLING FORMAT VARIATIONS IN X-RAY-DETECTORS BASED ON CHARGE-COUPLED-DEVICES

Three variations of charge coupled device (CCD) based x-ray detectors have been constructed and evaluated, two of which are used for routine data collection on small angle x-ray diffraction beamlines at Princet on. The first detector consists of a commercially available CCD camera system lens coupled to the output of a four-stage magnetically focuse d image intensifier. The second system, assembled to gather test data, consists of a CCD fiber-optically coupled to an x-ray conversion phos phor via a 5:1 reduction fiber-optic taper. The final detector configu ration was comprised of this fiber-optic taper system with the additio n of a single stage proximity-focused image intensifier. Rationale is given for choosing components to be used in the assembly of CCD-based detectors. (C) 1997 American Institute of Physics.
