Decreasing the operation temperature of a Silicon Photo-Multiplier (SiPM) leads to a drop in its dark noise. Some experiments consider cold temperatures as an option for low noise applications of SiPM. One of those is the TAO detector, which requires operation at $Tapprox -50~^circ$C. A significant dependence of the Photon Detection Efficiency (PDE) of a SiPM on different temperatures was reported with a drastic drop around this temperature. In this paper, we present studies of performance for two samples of SiPMs from Hamamatsu and AdvanSID(FBK) companies in a broad temperature range. No significant difference for the PDE was observed.
The performance of scintillator counters with embedded wavelength-shifting fibers has been measured in the Fermilab Meson Test Beam Facility using 120 GeV protons. The counters were extruded with a titanium dioxide surface coating and two channels fo
We report on the performance of silicon photomultiplier (SiPM) light sensors operating in electric field strength up to 30 kV/cm and at a temperature of 149K, relative to their performance in the absence of an external electric field. The SiPM device
In this work we study the performance of silicon photomultiplier (SiPM) light sensors after exposure to the JULIC cyclotron proton beam, of energy $sim$ 39 MeV, relative to their performance before exposure. The SiPM devices used in this study show a
A characterisation of scintillating fibres with silicon photomultiplier read-out was performed in view of their possible application in fibre tracking detector systems. Such a concept is being considered for the Kaos spectrometer at the Mainz Microtr
Radiation hardness is an important requirement for solid state readout devices operating in high radiation environments common in particle physics experiments. The MEGII experiment, at PSI, Switzerland, investigates the forbidden decay $mu^+ to mathr
