| In high-energy physics experiments, one of the largest and most important detector components is the calorimeter system. A calorimeter measures the energies of particles which encounter it. Several studies concerning calorimeters were performed.;The first study involved irradiation of a prototype calorimeter for the Compact Muon Solenoid (CMS) experiment at the future Large Hadron Collider (LHC). After irradiation, the calorimeter's performance was assessed, and a model describing the effects of irradiation on the calorimeter's performance was developed and tested.;The second study involved the calibration of a longitudinally segmented calorimeter. Testbeam data from the Plug Upgrade Calorimeter of the Collider Detector at Fermilab (CDF) were used to study different calibration methods, and a new method of calibrating the calorimeter system for hadron and jet detection was presented.;The third calorimeter study involved the assessment of a new method of measuring jets, sprays of particles produced from fragmenting quarks. In this method, the particle detector's tracking system is used in conjunction with the calorimeter to measure the energy of jets.;Finally, a search was performed for two jet decays of the W and Z bosons in a sample of dijet data taken by CDF during Run IC of the Tevatron, the world's highest energy particle accelerator located at Fermilab in Batavia, Illinois. The new calibration method for longitudinally segmented calorimeters, established in the calorimeter study described above, was successfully utilized in this search. |
