detectorresponse
Detector response refers to how a detector translates an incident particle or radiation into a measurable signal. It encompasses the relation between input energy or interaction type and the observed signal, including statistical fluctuations and instrumental effects. The central object is the detector response function R(S|E), the probability that an input of energy E produces a recorded signal S. The response also includes detection efficiency ε(E) and the detector’s energy and time resolutions.
Signal formation is a chain: energy deposition in the detector material, production of light or charge, collection
Calibration and characterization determine the response, using known sources or well-understood processes to establish the energy
Detector response varies by detector class. Scintillation detectors translate energy deposition into light and then into
