Pulse shape neutrons and gamma quanta discrimination by means of plastic scintillator of the new generation
Plastic scintillator (PS) of the new generation was developed for the pulse shape neutron and γ -quanta discrimination (n/γ -discrimination). To impart n/γ discrimination property two activation centers with different decay times were inserted in the PS. One of them transforms singlet excitation int...

| Summary: | Plastic scintillator (PS) of the new generation was developed for the pulse shape neutron and γ -quanta discrimination (n/γ -discrimination). To impart n/γ discrimination property two activation centers with different decay times were inserted in the PS. One of them transforms singlet excitation into fluorescent light, while the other – makes the same for triplet excitations. 1,4-Dimethyl-9,10-diphenylanthracene and tris(benzoylmethide) (1,10-phenantroline) Europium III – were used as activators. The figure of merit is 1.48 for this scintillator which is sufficient for reliable n/γ -discrimination. |
