Abstract

Arrays of 16 pixels of the Near UltraViolet High-Density thirdgeneration (NUV-HD3) Silicon Photomultipiers (SiPMs) produced by Fondazione Bruno Kessler (FBK) in collaboration with Istituto Nazionale di Fisica Nucleare (INFN) have been assembled and characterised to equip the prototype Schwarzschild-Couder Medium-Sized Telescope (pSCT) camera proposed for the Cherenkov Telescope Array (CTA) Observatory. Each camera module is composed by four 16-pixel optical units coupled with a 64-channel front-end electronics module. The prototype camera has been equipped with 24 of 177 modules and is currently taking data at the Very Energetic Radiation Imaging Telescope Array System (VERITAS) Arizona, since January 2019. Nine of the 24 modules mount FBK NUV-HD SiPMs. Latest results on their characterisation and performance will be shown. pSCT was able to detect its first light soon after the inauguration, in January 2019. A dedicated campaign for the Crab Nebula observation conducted in January 2020 led to the Crab detection. Results of this detection will be shown.
