Large-aperture TV detector with a beryllium-windowed image intensifier for x-ray diffraction

Abstract: 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) … Show more

“…The temperature of the sample was maintained at 37°C by an incubator, and the sample cell and stage were also set to 37°C. Using an x-ray image intensifier and cooled CCD detector (XR-IIϩCCD) (20), each scattering profile was collected for 1 s during which no radiation damage was found. The data were normalized to the intensity of the incident beam, and the buffer was subtracted.…”

“…The temperature of the sample solution was maintained at 25°C using a circulating water bath. Scattering patterns were recorded by a CCD-based x-ray detector, which consisted of a beryllium-windowed x-ray image intensifier (Be-XRII) (Hamamatsu, V5445P-MOD), an optical lens, a CCD image sensor, and a data acquisition system (Hamamatsu C7300) (14,15). The camera length was set to be 1485 or 2375 mm depending on the scattering-angle region to be observed.…”

“…A stable beam of photons with a wavelength of 1.50 Å was provided by a horizontally focusing bent-crystal monochromator and a vertically focusing mirror. 21 Scattering data were obtained with a CCD-based X-ray detector (Hamamatsu Photonics K.K., Hamamatsu, Japan) 22 and corrected for image distortion, nonuniform sensitivity and contrast reduction with an X-ray image intensifier before the analysis. 23,24 The detector was set at a distance of 1000±10 mm from the sample.…”
