Long term aging test of the new PMTs for the HL-LHC ATLAS hadron calorimeter upgrade
The central hadron calorimeter of the ATLAS experiment at the Large Hadron Collider (LHC) is readout by about 10,000 photomultipliers (PMTs). Earlier studies of performance showed a degradation in PMT’s response as a function of the integrated anode charge. A model of the time evolution of the PMT r...
