An Educational Experience with Linear Absorption Coefficient

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

In this paper is presented a simple procedure for evaluating the absorption coefficient of aluminum (Z = 13) using a gamma-emitting nuclide, highlighting the characteristics and limits that characterize the measurement. Using the educational kit caen, is possible to investigate the full potential of the adopted method. The results obtained give great confidence in the instruments and the aim of this work is to provide the first tools for conducting a good spectroscopic analysis.

Report on A.1.1 and B.1.5 experiments: a combined analysis

We report on a common analysis for the experiments of SiPM characterization (A.1.1) and comparison of dierent scintillating crystals: light yield, decay time and resolution (B.1.5). With this proposal, we use CAEN educational kit premium, based on SP5600 power supply and amplication unit connected to the SP5650C SiPM and the DT5720A digitizer. On one hand, we use the SP5601 LED driver. On another hand we use a 137Cs gamma source coupled individually to BGO, LYSO(Ce) and CsI(Tl) crystals with a constant volume (6x6x15 mm3). In the former case, we vary the amplitude (intensity) of the LED driver and verify the spectroscopic response. In the latter case, the light yield is due to a 137Cs gamma source interaction with the respective crystal, and again a spectroscopic response is analyzed. As a proof of concept, pulse high and pulse shape analyses are also proposed. Schematic comparisons of the results obtained with the three crystals are presented.

SiPM Spectrometer: detection of γ‐ray

Even if a SiPM is able to detect very low light intensity, it can be used for detecting a large amount of light in radiation detection with scintillators. The CAEN Mini Spectrometer is based on a Hamamatsu 3×3 mm2 SiPM, model MPPC S10362‐33‐050C, coupled to a scintillating crystal. This sensor, with its 3600 cells, provides a wide dynamic range, allowing the building of a mini spectrometer. Its Dark Count Rate (DCR), due to the large amount of pixels, is one order of magnitude higher than that of the 1×1 mm2; its Dark Count Rate at 0.5 ph. is 3÷4 MHz: this is not a problem for the spectrometer application because we are not interested in counting photons, but in measuring the electrical charge of the large pulse obtained by the pixels signal overlap. A right threshold will remove all the spurious hits.
