Description
We have studied the performance of the CMS hadron calorimeter using the testbeam
facilities at CERN. Two wedges of brass-scintillator calorimeter are exposed to
negative and positive beams with momenta between 3 and 300 GeV/c. Light produced in
the scintillators were collected using wavelength shifting fibres and read out using
Hybrid photodiodes. Each of the wedges had 17 layers of scintillators. In one of
these wedges signal from all 17 layers were grouped together while in the other each
layer was read out separately. The response, energy resolution, longitudinal and
lateral shower profiles are measured and compared with GEANT4 simulation results.
