Resumen

Silicon Photomultipliers (SiPMs) will be used in the focal planes of part of the telescopes of the Cherenkov Telescope Array (CTA), the next generation of Imaging Air Cherenkov Telescopes (IACT). Optical modules made of 4×4 SiPMs have been developed by Fondazione Bruno Kessler (FBK) and assembled in INFN laboratories, to be integrated on the prototype of a Schwarzschild-Couder Medium- Sized Telescope (SCT) proposed for CTA. As of today, a selection of 36 modules out of 56 working modules is ready for the integration on the telescope camera.
