摘要：

The response of a large BaF2 scintillator crystal in terms of analog output and energy resolution dependence on the light charged particles kinetic energy in the 4-150 MeV/u range has been investigated. The occurrence of loss mechanisms in the kinetic energy to light yield conversion is observed. A model calculation, based on the electron-hole recombination to trapping competition and the occurrence of ionization quenching, gives results in very good agreement with the experimental data. The detector energy resolution is found to be consistent with the photoelectron statistics as the main contribution. A procedure for reproducible particle energy calibration, based on the cosmic muon energy deposition in the BaF2 as reference is established.
