The EIGER2 XE CdTe 16M is the ultimate X-ray detector for high-energy applications. With its active area of 311 x 327 mm2 and its frame rate of up to 550 Hz, it is the largest — and, for its size, the fastest — commercially available high-energy photon-counting system. Optimally suited for diffraction of strongly absorbing materials, it offers highly efficient detection up to 100 keV for diffraction or scattering techniques such as Diamond Anvil Cell (DAC) experiments or macromolecular crystallography. DECTRIS top-notch technology has enabled a breakthrough in count-rate capability up to 107 photons/s/pixel, as well as in stability for cadmium-telluride detectors.
