We report on the beam test results of a photomultiplier tube (PMT) specially designed to suppress the signal due to Cherenkov light emitted by window glass when impacted by relativistic charged particles. This signal becomes a concern when it is comparable to the true PMT signal, especially in the case of calorimeters, where the response is at the level of a few photoelectrons per GeV. This design allows for placement of these PMTs behind the calorimeter without concern for hot spots from the Cherenkov background.
