Description
The CASTOR calorimeter of the Compact Muon Solenoid (CMS) experiment is
designed to study the very forward, baryon-rich region in heavy ion collisions
at CERN LHC. Together with the Zero Degree Calorimeter (ZDC) it will make
it possible to cover almost all the angular region for the CMS detector.
CASTOR consists of quartz plates in a heavy metal matrix. Cherenkov light
produced in the quarz plates will be detected by the Hamamatsu R5380Q
PMTs. All the PMTs which will be used in the calorimeter have to be verified
for gain and timing characterization to have the good performance required
by the CMS-CASTOR group before their installation into the calorimeter. We
established a testing station at Cukurova University for this purpose. In the
present paper after a brief description of the CASTOR calorimeter and its
physics goals we give our quality control test results of the PMTs, i.e. rise
time, pulse width, transit time, gain, etc.
