Abstract

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 $T \approx - 50^{\circ}$ 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.
