DOI: 10.1002/mp.15997
Abstract: Abstract Background All photon counting detectors have a characteristic count rate over which their performance degrades. Degradation in the clinical setting takes the form of increased noise, reduced material quantification accuracy, and image artifacts. Count… read more here.

DOI: 10.1007/s10909-018-2071-4
Abstract: We have developed an X-ray detector system based on Ta superconducting tunnel junctions (STJs) with an energy resolution below 10 eV under 1 keV. A principal advantage of STJs over other low-temperature detectors is their high count… read more here.

DOI: 10.1117/1.oe.57.3.031305
Abstract: Abstract. Using time-correlated single photon counting for the purpose of fluorescence lifetime measurements is usually limited in speed due to pile-up. With modern instrumentation, this limitation can be lifted significantly, but some artifacts due to… read more here.
