CDF END PLUG HADRON CALORIMETER UPGRADE - DESIGN, PRODUCTION AND QUALITY-CONTROL RESULTS

We present an overview of the CDF End Plug Upgrade Project. The struct ure of the upgraded calorimeter and the design of the optical readout system is discussed. We describe the production of scintillating tile/ fiber multi-tile assemblies (megatiles) and present the quality contro l results of megatiles produced for the CDF End Plug Upgrade Hadron Ca lorimeter. The sample of megatiles presented in this analysis correspo nds to approximately 16,500 individual tile/fiber assemblies. We discu ss the quality control requirements and present the distributions of t he quantities measured during the QC process. The various contribution s to the tile-to-tile light yield variations are isolated and discusse d.
