AbstractAbstract
[en] A method to produce polystyrene-based plastic scintillators with boron concentration from 0.38 to 5.0% has been developed. O-carborane was used as B-containing additive. The results of investigations of the optical, spectral and scintillation characteristics are presented and discussed. It is shown that 5% B-loaded scintillator has a light output as much as 70% relative to the unloaded one. High efficiency for thermal neutron registration achieved for produced samples makes it possible to use such scintillators in complex neutron high sensitive spectrometers. The measured level of radioactive contamination in these materials is good enough for using B-loaded scintillators in the proposed large scale neutrino experiments. (author)
