Query: Study of Silicon Photomultiplier Performance in External Electric Fields   We report on the performance of silicon photomultiplier (SiPM) light sensors
operating in electric field strength up to 30 kV/cm and at a temperature of
149K, relative to their performance in the absence of an external electric
field. The SiPM devices used in this study show stable gain, photon detection
efficiency, and rates of correlated pulses, when exposed to external fields,
within the estimated uncertainties. No observable physical damage to the bulk
or surface of the devices was caused by the exposure.
