New Effective Organic Scintillators for Fast Neutron and Short-Range Radiation Detection
Budakovsky, S.V.,Galunov, N.Z.,Karavaeva, N.L.,Jong Kyung Kim,Yong Kyun Kim,Tarasenko, O.A.,Martynenko, E.V. Professional Technical Group on Nuclear Science 2007 IEEE transactions on nuclear science Vol.54 No.6
<P>This paper describes the techniques used for making new organic scintillators and detectors based on these scintillators. Research has focused on designing large dimension organic scintillators to increase the efficiency of detecting ionizing radiation. The techniques described here have allowed us to produce (1) organic crystals of stilbene and p-terphenyl with diameters up to 120 mm and heights up to 100 mm; (2) p-terphenyl polycrystals doped with diphenylbutadiene molecules, as well stilbene polycrystals up to 250 mm in diameter and 5 mm in height; (3) the first prototypes of a composite scintillation material based on stilbene grains added to a silicone glue base, achieving a high efficiency of fast neutron detection.</P>
Some aspects of scintillation mechanism in organic molecular dielectrics
Galunov, N.Z.,Grinev, B.V.,Tarasenko, O.A.,Martynenko, E.V. The Korean Association for Radiation Protection 2005 방사선방어학회지 Vol.30 No.2
Aspects of the scintillation mechanism in organic systems obtained on the base of precise measurements of the radioluminescence pulse shape are discussed. It shown that the process of scintillation light pulse formation is mainly determined by initial conditions of exited states generation.
