Description

The DarkSide-20k experiment, a next-generation direct dark matter search using a dual-phase liquid argon time projection chamber, requires highly sensitive and radiopure light detection systems. This talk will present the production workflow and quality assurance procedures for the SiPM-based photo detection units (PDUs), developed specifically for DarkSide-20k. Each PDU is composed of 16 tiles, which are assembled and tested in a dedicated facility. We will discuss the PDU assembly process, characterisation techniques, and key performance metrics achieved during the cryogenic tests. The talk will also address the challenges of scaling up production to meet the demands of a 20-tonne active mass detector while ensuring uniform performance and long-term stability of the photodetector modules.
