Hybrid Photomultiplier tubes are an ideal tool for detecting small numbers of photons. However, as the number of photons increases, the probability of one or more of the resultant photo-electrons backscattering from the diode increases and eventually the individual photon peaks are no longer resolved. The spectra obtained are complex and the extraction of precise results depends on fitting a complex distribution. A function has been developed that provides an excellent fit to HPMT data and allows the extraction of precision results for the light collection uniformity from lead tungstate crystals for the CMS electromagnetic calorimeter end-caps.

Abstract Tests of a prototype for the electromagnetic calorimeter (ECAL) of the compact muon solenoid experiment (CMS) at the large hadron collider are described. The basic unit for the endcap ECAL in CMS is a “supercrystal” of 25 lead tungstate crystals. Results are presented from tests of the first full-sized supercrystal in electron beams and in a 3xa0T magnetic field. The supercrystal was exposed to electron beams with energies from 25 to 180xa0GeV. An energy resolution (σE/E) of (0.48±0.01)% was measured at 180xa0GeV.
