Abstract :
An array consisting of scintillating fibers embedded in a lead matrix was tested for use as a calorimeter for showers induced by energetic photons (50 MeV ≤ Eγ < 1 GeV). Experimentally, its efficiency was found to equal 100% for photon energies in excess of 100 MeV, the energy resolution is (σE) ≈ 10%(EγGeV)−12 over the full energy range. Extensive Monte Carlo studies show that the efficiency drops rapidly around Eγ = 40 MeV. The suitability of cosmic radiation for calibration purposes is demonstrated. Based on these studies design criteria for future arrays can be matched to experimental requirements.
