Abstract

Sastavljen je scintilacijski detektorski sustav za mjerenje života kozmičkih miona koji se temelji na silicijskim fotomultiplikatorima. Mjerenje je izvršeno korištenjem digitalizatora te su razvijeni i ispitani algoritmi za odredivanje visine, prikupljenog naboja i vremena pojavljivanja vrhova u električnim signalima. Pokazano je da silicijski fotomultiplikatori mogu imati problema s jako slabim signalima te da je te probleme moguće djelomično riješiti korištenjem koincidencijskih mjerenja. Odredivanje vremena života miona nije bilo uspje šno zbog problema s efikasnosti u prikupljanju scintilacijskog svjetla.

Abstract (english)

A scintillator detector system for cosmic muon lifetime measurement based on silicon photomultipliers was constructed. The measurement was performed using a digitizer and algorithms for determining height, collected charge and time of appearance of peaks in electrical signals were developed and tested. It was shown that silicon photomultipliers can have problems with very weak signals and that these problems can partly be solved by using coincidence measurements. Determining the muon lifetime was not successful due to efficiency problems in scintillation light collection.
