Position detector HyPix-Arc 100°

X-rayphotonarc

The HyPix-Arc 100° is a curved Hybrid Photon Counting (HPC) X-ray detector for single crystal diffraction applications. HyPix-Arc 100° offers a 17° larger capture angle compared to the flat HyPix 6000 detector. Collect more data in a single exposure with less reflection profile distortion: The HyPix-Arc 100° offers 100 degrees angular coverage from edge to edge. This is more than enough to collect complete single crystal diffraction data, according to IUCr guidelines, for even Cu Kα X-ray wavelength from a single theta position. High and low angle data are measured at the same time, under the same conditions for better scaling, faster data and reduced dose time. A curved detector minimizes peak distortion by ensuring that, even at short crystal-to-detector distances, diffracted beams are closer to perpendicular than is possible with a flat geometry. Like all HPC detectors, the HyPix-Arc 100° offers direct X-ray photon counting for every photon, single pixel top-hat point spread function with no readout noise and no dark noise. The 100 micron pixel size allows better resolution of reflections for long unit cells as well as improving reflection profile analysis. The HyPix-Arc 100° has a high frame rate of 100 Hz, as well as a Zero Dead Time mode providing the ultimate in error-free shutterless data collection. The advantage of direct detection found in the HyPix-Arc 100° is that no scintillator is required, and the size of the pixel determines the point spread function rather than the blooming that occurs on detectors with a scintillator. This means that reflections are sharper and more easily resolved.
