The EIGER detector series are x-ray detectors based on hybrid photon counting (HPC) technology. Originally developed by the Paul Scherrer Institute at the Swiss Light Source, they have been further developed and commercialized by DECTRIS. In an EIGER detector, X-rays are converted to electrical signals in a semiconductor subject to a high bias voltage. The generated signals are counted within the pixels of an ASIC which is bonded to the sensor. An amplifier, discriminator and digital counter are all embedded into each pixel with CMOS integrated circuit technology.

The direct detection of single photons and the accurate determination of scattering and diffraction intensities over a wide dynamic range have resulted in PILATUS detectors becoming a standard at most synchrotron beamlines and being used for a large variety of X-ray applications, including: small-angle scattering, coherent scattering, X-ray powder diffraction and spectroscopy.
