Silicon Photomultiplier (SiPM) Advanced Statistics

ED3127 – An Educational Kit Based on a Modular Silicon Photomultiplier SystemAn educational experiment based on a SiMP set-up is proposed in this Educational Note, guiding the student towards a comprehensive knowledge of this sensor technology while experiencing the quantum nature of light and exploring the statistical properties of the light pulses emitted by a LED.
ED3163 – Background removal procedure based on the SNIP algorithm for Gamma-ray Spectroscopy with the CAEN Educational KitA widely used method for subtracting the background under a photo-peak is provided by the Sensitive Nonlinear Iterative Peak (SNIP) algorithm. This Note reports a validation procedure of the SNIP algorithm, based on the invariance of the photo-peak area for different background levels.
ED3235 – A simple and robust method to study after-pulses in Silicon PhotomultipliersThis note describes a method for the characterization of the after-pulses in Silicon Photomultipliers. The after-pulsing probability in SiMP and its time constant are obtained measuring the mean number of photo-electrons in a variable time window following a light pulse. The method, experimentally simple and statistically robust due to the use of the Central Limit Theorem, has been applied to an HAMAMATSU MPPC S10362-11-100C.

A series of experiments covering several applications has been carried out and are presented in this section through detailed Educational Notes. The collaboration with the University of Insubria allows to offer experiments based on Silicon Photo-Multiplier detectors for advanced laboratories using the latest instrumentation generation developed by CAEN for the major experiments Worldwide.
For every topic, an accompanying suite is being developed, including an instructor’ guide, indications on the analysis and a library of routines in MATLAB, a platform widely distributed in the academic community.
