The effect of pulse rate on VPT response and the use of an LED light to improve stability
The Endcap Electromagnetic Calorimeter of the CMS detector at the LHC uses vacuum phototriodes (VPTs), which operate in the full 3.8T magnetic field of the experiment, to detect the scintillation light from the lead tungstate crystals. Initial measurements of the variation in response of VPTs, induc...
