Study of various photomultiplier tubes with muon beams and Cerenkov light produced in electron showers
2010
Abstract
The performances of PMTs of the CMS Hadron Forward calorimeter were studied when their windows were traversed by energetic charged particles to estimate the effects of the Čerenkov light production at the PMT Windows, which can interfere with the calorimeter signal. In order to find a viable solution to this problem, the response of four different types of PMTs to muons traversing their windows at different orientations was measured at the H2 beam-line at CERN.
The results of the data analysis are presented and discussed.
