Abstract

In this paper, the γ/n discriminability of LaCl3∶Ce scintillator is studied. This scintillator has high output(50000 photons/MeV) and fast principal decay time constant(～25 ns). γ/n discriminability of LaCl3∶Ce is 19.56 with MCNP calculation and larger than 19 in the experimental measurement with Dense Plasma Focus facility. The calculation is in agreement with the experiment result. This crystal may be applied to measuring the gamma pulse in the neutron and gamma mixed radiation field.
