ABSTRACT
This thesis consists of two parts: In the first part we describe the Photomul-
tiplier Tube (PMT) selection and testing processes for the Hadronic Forward (HF)
calorimeter of the CMS, a Large Hadron Collier (LHC) experiment at CERN. We
report the evaluation process of the candidate PMTs from three different manu-
facturers, the complete tests performed on the 2300 Hamamatsu PMTs which will
be used in the HF calorimeter, and the details of the PMT Test Station that is in
