Light yield Studies of the ATLAS Tile Calorimeter

The number of photoelectrons per unit of deposited energy Npe was determined for 6 Central Barrel modules of the TileCal/ATLAS detector. Test beam data from 2001 to 2003 of 180 GeV muon beams normal to the tile surface, are used. These results are compared with the light yield and PMT quantum effici...

Sumario:The number of photoelectrons per unit of deposited energy Npe was determined for 6 Central Barrel modules of the TileCal/ATLAS detector. Test beam data from 2001 to 2003 of 180 GeV muon beams normal to the tile surface, are used. These results are compared with the light yield and PMT quantum efficiency measured in laboratory with radioactive sources and LED respectively. The influence of the Npe on the energy resolution and signal to noise ratio is discussed.
