| Abstract | Abstract. The limited number of active pixels in a Geiger-mode Avalanche Photodiode (G-APD) results not only in a non-linearity but also in an additional fluctuation of its response. Both these effects are taken into account to calculate the amplitude resolution of an ideal G-APD, which is shown to be finite. As one of the consequences, the energy resolution of a scintillation detector based on a G-APD is shown to be limited to some minimum value defined by the number of pixels in the G-APD. PACS numbers: 85.60.Gz Keywords: avalanche photodiode, silicon photomultiplierOn the limited amplitude resolution of multipixel Geiger-mode APDs 2 Multipixel Geiger-mode avalanche photodiodes (G-APDs) [1] are solid state photodetectors with a fast growing field of applications. A G-APD can be thought of as a matrix of independent photon counters (pixels/cells) connected to a common load. A photoelectron produced in the G-APD volume by a photon can trigger an avalanche breakdown in one of the cells (fire the cell). To an input signal of n photoelectrons the G-APD responds with an output signal of N fired cells, the dependence N = f(n) |
