The Cherenkov Telescope Array (CTA) Consortium is developing the new generation of ground observatories for the detection of very-high energy gamma-rays.
The Italian Institute of Nuclear Physics (INFN) is contributing to the R&D of a possible solution for the Cherenkov photon cameras based on Silicon Photomultiplier (SiPM) detectors sensitive to near ultraviolet energies, produced by...

Silicon photomultiplier (SiPM), which consists of multiple pixels of avalanche photodiodes working in Geiger-mode (G-APD) is a promising semiconductor device in low level light detection for its excellent performances such as high response speed, low operated voltage, insensitive to magnetic field and small volume. The SiPM with epitaxial quenching resistors (EQR SiPM) using epitaxial silicon...

The gain of SiPMs increases with bias voltage and decreases with temperature. To operate SiPMs at stable gain, the bias voltage can be adjusted to compensate temperature changes.
We have tested this concept with 30 SiPMs from three manufacturers (Hamamatsu, KETEK, CPTA) in a climate chamber at CERN varying the temperature from 1°C to 50°C. We built an adaptive power supply that used a linear...

In the search for the nature of the neutrino, neutrinoless double beta decay (0νββ) plays a significant role in understanding its properties. By measuring the 0νββ decay rate with the desired sensitivity, it is hoped to verify the nature of the neutrino (Majorana or Dirac particle), lepton number violation and help determine the values for the absolute neutrino masses.

Analog silicon photo-multipliers (SiPMs) are now a mature technology in particle physics being widely used for the detection of scintillation and Cerenkov light. Digital SiPMs remain an emerging technology driven in part by the goal of achieving 10ps coincidence timing resolution for Positron Emission Tomography, which translates roughly to requiring photo-detectors with 10ps single photon...
