Silicon photomultiplier module as a photon detector for ACME III Electron EDM search

POSTER

Abstract

A search for the electron electric dipole moment (eEDM) is one of the powerful ways to probe for the existence of physics beyond the Standard Model of particle physics. The current upper limit of |de| < 1.1×10-29 e·cm has been achieved by the ACME II which used cold ThO polar molecules. One of the upgrade plans for the ACME III is a new light-induced-fluorescence detection system based on a silicon photomultiplier (SiPM) instead of photomultiplier tube (PMT). SiPMs have higher quantum efficiency, ~50% at 512 nm, than the normal PMTs used in ACME II. We report here a design of the SiPM module and the characterization of the performance.
