Abstract
V sklopu zaključne naloge se ukvarjamo z detekcijo sevanja hitrih in termičnih nevtronov na podlagi polprevodniških detektorjev iz silicijevega karbida. V začetku smo sestavili merilno vezje za uspešno detekcijo nabitih delcev in ga preizkusili na delcih alfa, $^{241}$Am. Temu je sledila uporaba $^6$LiF in $^{10}$B$_4$C nevtronskih pretvornikov, s katerima smo izmerili spekter nabitih delcev, ki nastajajo ob interakcijah hitrih in termičnih nevtronov. Na koncu smo občutljivost detekcije nevtronov razširili s paralelno vezavo dveh in štirih detektorjev.

Title:Measurement of Fast and Thermal Neutrons with Silicon Carbide Semiconductor Detectors
Abstract:
As a part of my thesis, we experimented with the detection of fast and thermal neutron radiation using semiconductor detectors made of silicon carbide. Initially, we assembled a measuring circuit for the detection of charged particles and tested it with an alpha particle emitter, $^{241}$Am. This was followed by the use of $^6$LiF and $^{10}$B$_4$C neutron converters, with which we measured the spectrum of charged particles resulting from interaction of fast and thermal neutrons. In the end, we expanded the sensitivity of neutron detection by connecting the circuit with two and four detectors in parallel.

Keywords:semiconductor detector, neutron converter, radiation, neutron, energy spectrum
