Kozmik ışınların algılanmasının uygulamasında silikon fotoçoğaltıcıların çalışılması

In this thesis, a study of prototypes based on a silicon photomultiplier (SiPM) coupled with scintillator detector in order to use on the applications of astropar- ticle physics is presented . One of the SiPM that is provided by SensL company is used at the terrace of Sphinx Observatory (Switzerland) for developing the proto- type detector which will be used in TAU shoWER (TAUWER) array experiment. The other SiPM provided by FBK company is planned to use in camera system of Cherenkov Telescope Array (CTA). Theoretical and practical application of the detection method intended for using in the construction of a new high efficient TAUWER experiment in order to observe the tau-neutrino ντ is discussed in this thesis. An investigation of SiPM characterization was performed to determine the optimum conditions of a novel SiPM detector prototype. A series of mea- surement was established in a fast and reliable way with high precision in order to characterize SiPMs. Characterization tests such as gain, dark noise, optical crosstalk, afterpulsing measurements (dynamic) and forward IV measurement (static) are crucial for the operation of the SiPM. There is a big collaboration ef- fort in INFN to improve the applications of SiPM produced by FBK. This SiPM is used to develop a readout system for detecting the Cherenkov lights and will be assembled to the CTA camera system in the future. The prototype detector working at the terrace of Sphinx Observatory is also used to correlate the rate of the cosmic ray with solar weather parameters.
