Abstract
An estimation of the photon detection efficiency of multi-pixel Geiger-mode avalanche photodiodes based on measurements of their response to low-intensity light is presented. Properties of detectors manufactured by different producers are compared. A new fit method of the response spectra to light, taking into account after-pulse and cross-talk effects is proposed to yield the initial number of photons. The value of photon detection efficiency is calculated using a calibrated photodetector as a reference. The sources of systematic error are discussed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
