Abstract

<jats:p>A large-aperture (150 mm and 230 mm in diameter) x-ray TV-type detector has been developed for x-ray diffraction with synchrotron radiation. The detector consists of a beryllium-windowed x-ray image intensifier, an optical lens, a charge coupled device (CCD) image sensor, and data acquisition system. The spatial resolution is 270 μm(FWHM), and the dynamic range is 6000:1. The noise level is quantum limited. The nonuniformity of response and image distortion is corrected by software. When a TV-rate (NTSC-mode) CCD is used as an image sensor, time-resolved measurements with a rate of 30 frame/s can be achieved with its noise quantum limited.</jats:p>
