Characteristics of lead-scintillator sampling shower counters for the detection of electrons and photons in the energy range 70 MeV to 6 GeV

Abstract 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 parameters was investigated. Typical resolutions obtained were σ ⋍ 7%/E 1 2 (in GeV) for photon or electron energies, and σ x ⋍ 11 mm /E 1 2 (in GeV) for the impact position.
