Description
This contribution presents an update on the Photon Detection Module (PDM) R&D for large-scale noble liquid experiments and precise timing systems. Based on a multilayered silicon interposer, for radio purity and coefficient of thermal expansion matching between its components, the PDM has built-in modularity for system scaling. It is based on an array of Photon-to-Digital Converters (PDCs, a.k.a. digital SiPMs), which have advantages over analog SiPMs by using the boolean nature of Single Photon Avalanche Diodes (SPADs). The PDM also includes a tile controller for digital signal processing, timestamping and to manage the various components. Then a power management integrated circuit is required to bias the SPADs and the PDM components. Finally, a laser-less silicon photonics-based communication module is integrated to interface with the data acquisition system. The implementation status, challenges and benefits of each component will be discussed.
