Description
The Cherenkov Telescope array (CTA) will represent the new generation of Imaging
Atmospheric Cherenkov Telescopes (IACTs), aimed to detect very high energy gamma-rays
produced in atmospheric showers. The prototype Schwarzschild-Couder Telescope (pSCT) has
been inaugurated in January 2019 at the Fred Lawrence Whipple Observatory aiming to the
extention of the CTA array baseline.
Silicon Photomultipliers are particularly suitable as optical units of IACTs to detect the low
and fast-intensity Cherenkov signal. The Near UltraViolet High Density 6x6 mm2 SiPMs
(NUV-HD3), produced by Fondazione Bruno Kessler in collaboration with INFN, have been
assembled in more than 100 arrays of 16 pixels. These optical modules have been characterized
in the laboratories of INFN to be integrated on the camera of pSCT.
In this contribution we report the characterization results of the SiPM arrays and on the
uniformity of their performances.
