一种可能性，制造塑料的中子/γ脉冲形状歧视（PSD）的证明，使用系统的聚乙烯基甲苯（PVT）聚合物基质负载有一个澄清染料，2，5-二苯基恶唑（PPO）。从激发态相互作用和延迟光形成的经典模型出发，讨论了液体和固体有机光催化剂中PSD上升条件的异同。第一个表征结果表明，PSD在塑料制冷剂可以是类似的幅度，甚至高于标准的商业液体制冷剂。(C)2011 Elsevier B. V.保留所有权利。
A possibility of manufacturing plastic scintillators with efficient neutron/gamma pulse shape discrimination (PSD) is demonstrated using a system of a polyvinyltoluene (PVT) polymer matrix loaded with a scintillating dye, 2,5-diphenyloxazole (PPO). Similarities and differences of conditions leading to the rise of PSD in liquid and solid organic scintillators are discussed based on the classical model of excited state interaction and delayed light formation. First characterization results are presented to show that PSD in plastic scintillators can be of the similar magnitude or even higher than in standard commercial liquid scintillators.
