Description
In neutrino experiments, photomultiplier tubes (PMTs) in water or liquid scintillators are frequently used to measure a signal of light. Dark pulses of the PMTs are an important background which affects low energy measurements. It is known that the dark pulse rate depends on temperature and magnitude of the electric-field around the photo cathode. To find optimal settings in the actual environment, I measure these dependences and represent the dark rate with a theoretical model.
