On the Light Yield Decreasing by Time of the Scintillation Counters of the Muon Trigger at CDF
The Muon System at CDF has an important role for investigation of processes with heavy quarks. Efficient functioning of the scintillation counters, considerably contributory to the CDF muon triggers, is a necessary condition for taking good data. The results of the long-term measurements of the light yield collected at the far from photomultiplier end of the various types of scintillation counters are presented. The goal of this study is to estimate life length of effective operation for these counters in experiments.
