    "abstract": "In low background and low threshold particle astrophysics experiments using\nobservation of Cherenkov or scintillation light it is common to use pairs or\narrays of photomultipliers operated in coincidence. In such circumstances, for\ninstance in dark matter and neutrino experiments, unexpected PMT noise events\nhave been observed, probably arising from generation of light from one PMT\nbeing detected by one or more other PMTs. We describe here experimental\ninvestigation of such coincident noise events and development of new techniques\nto remove them using novel pulse shape discrimination procedures. When applied\nto data from a low background NaI detector with facing PMTs the new procedures\nare found to improve noise rejection by a factor of 20 over conventional\ntechniques, with significantly reduced loss of signal events.",
