Description

DarkSide-20k is a proposed 30-tonne fiducial mass liquid argon TPC that will perform an instrumental background-free search for WIMP dark matter. The TPC will be outfitted with 200,000 silicon photomultipliers (SiPMs) grouped into 8,280 single-channel, 25 cm$^2$ photosensors that are sensitive to single photoelectrons. We will present the cryogenic performance of the first DarkSide Motherboard, a 625 cm$^2$ module that houses 25 photosensors and their associated low-noise electronics. We will also discuss the strategy for producing the full complement of DarkSide photosensors, including the transition of wafer production to a commercial foundry and the construction of a dedicated, low-background packaging facility.
