PMT Rate Tests
We test the signal output of the Hamamatsu PMT assembly H10534MOD. This is based on a 10 stage tube with two outputs. The test are performed using a reference PMT assembly in a laser beam where the light output of the laser is adjusted to generate a signal in the reference PMT assembly that is similar to what is seen by the PMTs in the TOF paddle at 1550V operating voltage.
