The TileCal Laser calibration system
TileCal is the central hadronic calorimeter of the ATLAS detector operating at LHC. It is a sampling calorimeter whose active material is made of scintillating plastic tiles. Scintillation light is read by photomultipliers. A laser system is used to monitor their gain stability. This note describes...

| Sumario: | TileCal is the central hadronic calorimeter of the ATLAS detector operating at LHC. It is a sampling calorimeter whose active material is made of scintillating plastic tiles. Scintillation light is read by photomultipliers. A laser system is used to monitor their gain stability. This note describes two complementary methods used to measure stability in time of the photomultipliers gain. |
