This guide outlines the assembly steps for a Multi-PMT system featuring a 12+19-3” sensor. The process includes moulding the optical layers, evacuating to 0.8 bar absolute pressure, and applying necessary electronics and cables, including the Faraday shield logic board. Steps involve mounting boards, preparing and sealing the top and bottom sphere halves, connecting components, and securing the heatsink. Quality control and relevant tests are conducted between steps, culminating in final tests to ensure system integrity and performance.
