Investigation of a total absorption lead-glass Cherenkov γ-spectrometer in the energy range 0.25–4.0 GeV
1966
Abstract The possibility is studied of using lead-glass Cherenkov spectrometers of relatively small size (18 × 18 × 30 cm 3 ), to measure the energy of gamma-quanta above 1 GeV. The spectrometer has been calibrated using monoenergetic electrons of energy 0.25, 0.5, 2.0 and 4.0 GeV. Within this range the γ-spectrometer has a linear dependence of Cherenkov pulse amplitude with energy and a high-energy resolution (half-width at half-maximum) of ±5% for electrons with E e = 4 GeV.
