N2 - This report shows the design and performance of a large area Silicon Photomultiplier (SiPM) module developed for the detection of fluorescent light emitted from a ∼1 liter scale volume. The module was optimized for the planned ACME III electron electric dipole moment (eEDM) search, which will be a ∼10 TeV probe for the existence of physics beyond the Standard Model of particle physics. The ACME experiment searched for the eEDM with the world's highest sensitivity using cold ThO polar molecules (ACME II (Andreev et al., 2018 )). In ACME III, SiPMs will be used for detection of fluorescent photons (the fundamental signal of the experiment) instead of PMTs, which were used in the previous measurement. We have developed an optimized SiPM module, based on a 16-channel SiPM array. Key operational parameters are characterized, including gain and noise. The SiPM dark count rate, background light sensitivity, and optical crosstalk are found to all be well suppressed and more than sufficient for the ACME III application.
