摘　　要：为提高塑料闪烁探测器对低能中子的探测灵敏度,根据中子灵敏度补偿原理研制了载6L i塑料闪烁探测器。利用串列加速器中子源对几种新研制的载6L i塑料闪烁探测器中子能量响应进行了实验标定,获得了几种掺不同6L i浓度的塑料闪烁探测器的中子能量响应曲线。实验结果表明,载6L i塑料闪烁探测器对低能中子确有较高的探测灵敏度。A new plastic scintillator, plastic scintillator loaded ^6Li, is brought forward and developed in this paper in order to increase low energy neutron sensitivity. Neutron sensitivity of several plastic scintillation detectors loaded ^6Li new developed in neutron energy range 0. 2MeV～5.0MeV are calibrated by direct current at serial accelerator. Energy response curves of the detectors are obtained in this experiment. It is shown that this new plastic scintillation detector can increase low energy neutron sensitivity in experimental results.
