With its large sensor area of 233 x 244 mm2, the EIGER2 XE CdTe 9M is the ideal X-ray detector for high-energy X-ray diffraction, diffuse scattering, powder diffraction, pair distribution function analysis, and other applications. It can operate continuously at frame rates of up to 550 Hz, which enables time-resolved and in situ experiments that are free of image lag. Noise-free single-photon counting and the direct-conversion sensor’s sharp point spread function allow weak signals next to strong peaks to be measured with the best possible signal-to-noise ratio, yielding highly detailed images.
