Quality control of the production of the hadron calorimeter for the CDF End Plug Upgrade

We summarize the quality control results of scintillating tile/fiber multi-tile assemblies (megatiles) produced for the CDF End Plug Upgrade Hadron Calorimeter. The sample of megatiles presented in this analysis corresponds to approximately 12500 individual tile/fiber assemblies produced and tested. We discuss the quality control requirements and present the distributions of the quantities measured during the QC process. The various contributions to the tile-to-tile light yield variations are isolated and discussed.<
