Erasmus Mundus Program: Quantus software detector’s calibration and efficiency curve

September 24th, 2021| |CAEN Experiments, Gamma Spectroscopy, Nuclear Physics and Radioactivity, Nuclear Physics and Radioactivity

Detectors need calibration before starting data acquisition in both energy and full width half maximum of the signal (FWHM). The first requires multiple known energy peaks so several gamma sources are used, while the second is related to the fact of having Gaussian distribution shapes in the spectrum centred in the peak energy instead of a sharp shape. All the spectra collected and calibration done bring the possibility of calculate the efficiency of the detector, which is a curve showing the relation between energy and efficiency. Thanks to that curve scientists are able to set the best conditions for the acquisition, as well as to determine the activity of an unknown source. Quantus is CAEN high performance software to make Quantitative Spectrometry with Hexagon digital MCA. It permits working with many spectra at the same time. Since it allows setting parameters in the hardware, collecting data and analysing them, it is a useful tool for calibration purpose.

Erasmus Mundus Program: Environmental Measurements with iSpector

September 24th, 2021| |CAEN Experiments, Environmental radioactivity

In this report the radioactivity measurement of samples usually found in the environment was studied, using iSpector Digital (Intelligent Silicon Photomultiplier Tube with Digital MCA). After the energy calibration of the system based on LYSO crystal and the calibration verification and tuning with Potassium Chloride sample, the data analysis of the Pozzolana Sample Spectrum as well as the Background measurement was done. Furthermore, the test sample radiation was identified.

Erasmus Mundus Program: Characterization of SiPMs

September 24th, 2021| |CAEN Experiments, Particle Detector Characterization, Particle Detectors Characterization, Silicon Photomultipliers

In this report the characterization of a Silicon Photo-Multiplier (SiPM) detector was done in order to estimate the main features of the detector. The breakdown voltage, the gain, the dark Count Rate as well as the optical crosstalk of the detector were successfully obtained.
