Dectris Eiger hybrid photon counting detector series

Dectris introduces the hybrid photon counting (HPC) detector series Eiger. The product line features 75 µm pixels and a frame rate of several kHz. The detectors feature neither readout noise nor dark current for best signal-to-noise ratio; small pixels and good point-spread function for high spatial resolution; and continuous readout and global shutter for high duty cycles. The line-up ranges from 1 to 16 MP systems and is available in two performance classes.

The EIGER R 1M is claimed to be the first high-resolution hybrid photon counting detector for the laboratory, combining renowned single-photon sensitivity with high resolution. The product features a megapixel sensor with a pixel size of only 75 µm, turning it into a versatile tool for X-ray detection in a variety of laboratory applications. The user can exploit the single-pixel point-spread function to resolve large unit-cell protein crystal axes or to record high-resolution powder diffraction patterns from textured samples.

The EIGER X series provides high performance for demanding synchrotron applications, with frame rates in the kHz range in combination with continuous readout making the product suitable for time-resolved experiments and XPCS. Hitherto prohibitively slow scanning beam imaging techniques like ptychography become routinely possible. High-resolution and coherent diffraction experiments benefit from the small pixel size and a point-spread function that is enabled by direct conversion of X-rays. High count rates per unit area match the increasing beamline brightness.
