塑料闪烁体探测器性能比较

Performance Comparison of Plastic Scintillator Detectors

采用MC模拟了对溶剂BC408、PMMA(聚甲基丙烯酸甲酯)、PS(聚苯乙烯)、乙烯基甲苯、LiME(甲基丙烯酸锂)共5种材质的塑料闪烁体在不同射线能量下的性能参数测试,并将实验数据进行对比,进而选出光产额与探测效率较高的产品.实验结果表明:BC408塑料闪烁体在能量区间为0~0.662 MeV的射线照射下的光产额与探测效率皆比其他4种材质更为稳定,适用性更强.此次试验结果可为使用选取探测器提供参考.

Monte Carlo simulation method was used to simulate 5 plasticscintillators which are under different ray energies,including BC408,poly methacrylate(PMMA),polystyrene(PS),vinyl toluene and lithium methacrylate(LiME).And their performance parameters were tested to select products with higher light yield and detection eficiency.The experimental results show that the light yield and detection effciency of the BC408 plastic scintillator under the radiation of 0 to 0.662 MeV are more stable and more applicable than the other four materials.The test results can provide a reference for the use of selected detectors.
