SiPM Spectrometer: detection of γ‐ray

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

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.

Applications of Digital Pulse Acquisition Systems and Software Defined Electronics (SDE) in Advanced Teaching Labs

The CAEN DT5790N is a digital acquisition system which houses two high voltage supplies and two highspeed (12bits, 250MHz) waveform (pulse digitizers. These in tandem with the use of post processing software combine to produce a Software Defined Electronics (SDE) system that can be used in several advanced teaching experiments. FPGAs and built-in software can be used to display the pulse waveform and produce a time-stamped output (4 ns intervals) in a text list for post processing, e.g via MATLAB, Python, LabView, ROOT, BASIC, etc. The SDE can than be reconfigured as neeeded and used to run many nuclear and other expermiments in an advances teaching lab course. This serves to expose students to modern state-of-the-art data acquisition technology. Experiments such as Fission Neutron, Time-of-Flight, Comptron Scattering, Co-60 Gamma Coincidence, Na-22 Gamma-Gamma Annighilation. Muon Lifetime, etc. are well suited for SDE. The SDE system also provides a very adaptive and cost-effective substitute for NIM or CAMAC electronics as SDE can be easily set up with only a single digitizer box and a computer for many different experiments. Typical data using the SDE application we have developed for several advanced teaching lab experiments will be shown. Several other digitizers similar to the CAEN unit are also available for SDE.
