photon-counting detector

photon-counting detector

A highly sensitive detecting system with a very high time resolution and very low readout noise. Many photon counters use an image tube or microchannel plate as a first stage to intensify the incident beam of light or other radiation, and a CCD array as the final detector. The earliest version was Boksenberg's IPCS.

A powerful X-ray source sends a beam through a sample to a sensitive photon-counting detector without the need for an image-forming lens.
So the group slowed the flow rate from 10 meters per second to 10 millimeters per second, keeping the fragments and the dye bound to them in the light source for a longer period so more photons could be emitted, collected, and measured using a solid-state photon-counting detector.
Linear array photon-counting detectors with energy resolution are positioned perpendicular to the beam propagation direction for X-ray fluorescent spectra [11].
Iwanczyk and Iniewski provide the current status of key technologies and applications of photon-counting detectors emerging in medical imaging.
