For high-energy applications, X-ray detection efficiency is limited by the thickness of the silicon sensor, which converts the X-ray photons into an electrical charge. High-energy sensors with increased sensor thicknesses of 1000 µm compensate for silicon’s lower absorption efficiency at high energies.
All DECTRIS silicon sensors are based on well-established silicon technology. They are available in the MYTHEN2 and PILATUS detector families — from the MYTHEN2 1K to the PILATUS 6M. EIGER detectors incorporate our standard 450 µm silicon sensors.
