Characteristics of Lead-Scintillator Sampling Shower Counters for the Detection of Electrons and Photons in the Energy Range 70 MeV to 6 GeV

摘要

A lead-scintillator shower counter using fluorescent radiation converters to collect scintillation light was tested with electrons and photons in the energy range 70 MeV to 6 GeV. The influence of the various design paramters was investigated. Typical resolutions obtained were sigma approx. equal to 7%/ sqrt E (in GeV) for photon- or electron energies, and sigmasub(x) approx. equal to 11 mm/ sqrt E (in GeV) for the impact position.
