Abstract
A new scintillator material for the detection of fast neutrons that consists of a methanol adduct of cerium trichloride with the composition CeCl3(CH3OH)4 has been characterized using 14.1 MeV neutrons from a deuterium-tritium neutron generator and fast neutrons from a bare instrumented 252Cf source. The timing resolution of the scintillator for fast neutrons was found to be ̃ 1 ns. Neutron interactions in the CeCl3(CH3OH)4 composition were simulated using the MCNP-PoliMi code. These simulations indicate that proton recoils account for most of the deposited energy in CeCl3(CH 3OH)4. The crystalline molecular adduct CeCl 3(CH3OH)4 represents a rare-earth metal-organic scintillator that can be applied to both fast neutron and gamma-ray detection.
