Abstract

Cilj ovog diplomskog rada bio je napraviti demonstracijski postav pomoću kojega možemo detektirati odnosno opaziti X-zračenje i koji bi se mogao koristiti u studentskom laboratoriju. Princip rada postava temelji se na interakciji gama zraka sa materijalom fotoelektričnim efektom, nakon kojeg se iz danog materijala emitira X-zračenje, koje se potom detektira i analizira. Kao detektor, korišten je GAGG scintilacijski kristal, očitavan silicijskim fotomultiplikatorom spojen na CAEN A1702 uređaj za analizu signala, a kao izvor gama zračenja korišten je 137^Cs. Opažanja su izvršena na nekoliko različitih materijala; Pb, Cu, i Al, kako bi se ispitala eksperimentalna metoda. U mjerenjima su uspješno opažene X-zrake iz olova, dok one iz Cu i Al nije bilo moguće pouzdano detektirati zbog visoke osjetljivosti uređaja na energijama manjim od 15 keV.

Abstract (english)

The goal of this thesis was to create a demonstration setup with which we can detect or perceive X-radiation and which could be used in a student laboratory. The principle of operation of the setup is based on the interaction of gamma rays with the material through the photoelectric effect, after which X-radiation is emitted from the given material, which is then detected and analyzed. As a detector, a GAGG scintillation crystal was used, read by a silicon photomultiplier connected to a CAEN A1702 signal analysis device, and 137Cs was used as a source of gamma radiation. Observations were made on several different materials; Pb, Cu, and Al, to test the experimental method. In the measurements, X-rays from lead were successfully observed, while those from Cu and Al could not be reliably detected due to the high sensitivity of the device at energies below 15 keV.
