Abstract
Two NE213 liquid scintillation detectors of 206 and 412 cm(3) in volum e were calibrated in high-energy photon fields (E-gamma > 7 MeV at the PTB accelerator facility. The measured pulse height spectra are in ex cellent agreement with the response functions simulated with the EGS4 Monte Carlo code. The generally assumed linear dependence of the elect ron light output on the energy deposited does not hold for electron en ergies above 1.6 MeV. The nonlinear electron light output function was therefore included in the calculation of the response functions. The production of high-energy electrons and positrons in the target assemb ly and in the air was also taken into consideration.
