Outstanding count-rate performance
EIGER combines a smart design for fast single-photon counting with small pixel size. This achieves exceptional count-rate performance per area. Count rates of more than 500 million counts per second and square millimeter or 3 million counts per second and pixel can be accurately measured with EIGER. The left hand plot shows observed count rate as a function of incoming rate for different X-ray energies, measured with a threshold of half the X-ray energy.
While EIGER benefits from its small pixel size, PILATUS3 takes advantage of DECTRIS instant retrigger and the properties of a non-paralyzable counter. This way, both detector families achieve similar, excellent count rate performance per area. The right hand plot shows count rate performance of EIGER and PILATUS3 measured at an X-ray energy of 10 keV with a threshold of half the X-ray energy.
