- PILATUS is the name of a series of x-ray detectors originally developed by the Paul Scherrer Institute at the Swiss Light Source and further developed and commercialized by DECTRIS. The PILATUS detectors are based on hybrid photon counting (HPC) technology, by which X-rays are converted to electrical signals by the photoelectric effect in a semiconductor sensor layer—either silicon or cadmium telluride—which is subject to a substantial bias voltage. The electric signals are counted directly by a series of cells in an ASIC bonded to the sensor. Each cell—or pixel—is a complete detector in itself, equipped with an amplifier, discriminator and counter circuit. This is possible thanks to contemporary 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.
