Project Title: 

Studying the behavior of SiPMs

Project Description: 

To further study the fundamental particles of nature we need to develop new instrumentation. A new technology that can help achieve that goal is the use of Silicon Photomultipliers (SiPMs) to detect photons produced in scintillating fibers. Two instruments that will help achieve this goal is by using: Scintillating Fibers and Silicon Photomultipliers (SiPM). There are two aspects of SiPM performance that have been studied in this work. The signal output from the SiPM increases with higher bias voltage, but so does the noise. We have measured this increase to allow optimization of the bias voltage setting. The second study performed is development of software using GEANT4 to simulate the response of the detector (fiber+SiPM) to incoming particles. With this simulation we compare the simulated response with the response measured in the detector to make sure that we have everything functioning well.
