Abstract

The ASTRI Mini-Array is an International collaboration led by the Italian National Institute for Astrophysics (INAF), that will operate nine telescopes to perform Cherenkov and optical stellar intensity interferometry (SII) observations. At the focal plane of these telescopes we are planning to install a stellar intensity interferometry instrument. Here we present the final selected design, based on Silicon Photomultipliers (SiPMs) detectors matching the telescope point spread function together with a dedicated front end electronics.
