Highest count rates

PILATUS3 R features DECTRIS instant retrigger technology, which enables non-paralyzable counting and highly accurate count rate correction. The count rate performance closely matches the response of an ideal detector (Fig. 1) at high intensities of up to 1 Mcps per pixel. Thanks to a simple yet precise mathematical model, the small deviations at extreme intensities of 2 Mcps per pixel and above can be easily and accurately corrected for. Both local and global count rates of PILATUS3 detectors are far superior to those of counting detectors based on gas discharge or similar technologies. PILATUS3 detectors are compatible with even the most demanding samples such as strongly diffracting small molecule crystals.

Fig. 1: Count rate performance of PILATUS3 R CdTe detectors. The graph shows the measured (open circles) and theoretical (solid line) count rate performance of PILATUS3 R CdTe detectors across the X-ray intensity range relevant for laboratory experiments in millions of counts per second (Mcps) and pixel. PILATUS3 R CdTe closely matches the response of an ideal detector (dashed line) at high intensities of up to 1 Mcps per pixel. Thanks to a simple yet precise mathematical model, the small deviations at extreme intensities of 2 Mcps per pixel and above can be easily and accurately corrected for.
