Description
Two identical Zero Degree Calorimeters (ZDCs), designed to measure
neutrons and very forward photons in the heavy-ion and low luminosity pp
collisions at the LHC, are located at ±140 m from the CMS interaction point.
Each ZDC consist of two independent compartments: the electromagnetic
(EM) and hadronic section (HAD). The calorimeter sections are sampling
calorimeters, and core of structure consists of a tungsten plate / quartz
ribbon stack which is readout by PMT. Significantly, the calorimeter will be
very compact, extremely fast and radiation-hard. We present results on the
linearity and the energy resolution of the ZDCs using high energy positrons
and pions from the 2006 test beam run at the CERN H2 beam line.
