We have developed a custom amplifier board coupled to a large-format16-channel Hamamatsu silicon photomultiplier device for use as the light sensorfor the electromagnetic calorimeters in the Muon g-2 experiment at Fermilab.The calorimeter absorber is an array of lead-fluoride crystals, which producesshort-duration Cherenkov light. The detector sits in the high magnetic field ofthe muon storage ring. The SiPMs selected, and their accompanying customelectronics, must preserve the short pulse shape, have high quantum efficiency,be non-magnetic, exhibit gain stability under varying rate conditions, andcover a fairly large fraction of the crystal exit surface area. We describe anoptimized design that employs the new-generation of thru-silicon via devices.The performance is documented in a series of bench and beam tests.
