The “Advanced Particle–astrophysics Telescope” (APT) is a mission concept for a future space-based MeV-TeV observatory, that will combine a Compton and e+e− pair telescope. A small-scale prototype, the “Antartic Demonstrator for APT” (ADAPT), is currently being developed to fly on balloon in Antarctica during the local 2025-2026 flight season. Among its subdetectors there is a hodoscope that consists of four layers of interleaved scintillating fibers coupled to Silicon Photomultipliers (SiPMs). A multichannel electronics is essential for this kind of device: specifically the SMART (SiPM Multichannel ASIC for high Resolution Cherenkov Telescopes) ASIC, characterized by compactness, low cost, good level of integration of the electronics, will be employed for the amplification of signals coming from the SiPMs.
