31. After decommissioning, MACRO donated about 800 photomultiplier tubes to the Daya Bay Reactor Neutrino Experiment. 32. The light is focused onto the photocathode of a photomultiplier tube that triggers an electron avalanche. 33. Are the photomultiplier tubes operated continuously? 34. The color decoder electrically subtracted the signal from the photomultiplier from the existing color burst signal. 35. A photomultiplier detected the light beam. 36. The fluorescence signal is captured by a photomultiplier a known distance downstream of the de Laval nozzle. 37. Some portion of these low-energy photons arrive at the photocathode of an attached photomultiplier tube. 38. A photomultiplier and associated electronics counts the photons that are proportional to the amount of NO present. 39. In 1978 and 1980, the Oxford-group around Colin Sheppard and photomultiplier tubes as detectors. 40. The timing of each signal from each photomultiplier told the approximate path and speed of the particle.
