Abstract--The builders of the CMS forward hadron calorimeter
established a set of specifications for readout PMTs that reflected
the physics goals and mechanical needs of the CMS experiment.
Three manufacturers, Hamamatsu, Photonis (Philips), and Elec-
tron Tubes (EMI), provided candidate PMTs based on these initial
requirements. Timing, gain, dark current properties, and single
photoelectron spectra of these candidate PMTs were measured.
Results show that Hamamatsu PMTs (R7525HA) conform best to
the specifications of the Hadron-Forward (HF) Calorimeter.
Index Terms--Calorimetry, Cherenkov light, CMS, CMS
Hadron-Forward (HF) calorimeter, high-energy physics experi-
ment, photomultiplier tube, PMT, single photoelectron spectrum
(SPES).
