摘要: 波移光纤是闪烁体中子探测器的重要组成部分，其性能参数——光衰减长度、光损失率和光吸收重发射效率等将直接影响探测器的性能。本研究利用一套光纤性能测试试验装置，系统地研究了BCF91A 型波移光纤的光传输性能。结果表明：BCF-91A 型波移光纤光衰减长度为(1485) cm，吸收重发射效率约为5.6%；当光纤转弯半径为20 mm，长度为1.1 m时，其性能可以满足闪烁体中子探测器要求；BCF-91A 型波移光纤是很好的光纤候选材料.The position-sensitive scintillator neutron detector (SSND) with high efficiency, high resolution and high n/ discriminate ability etc., is developed to replace the traditional 3He neutron detector. The wave-length shifting fibers (WLSF) are used in SSND. The performances of BCF-91A type WLSF, such as attenuation length, bend loss and lights transportation ability etc., are studied in this paper. The attenuation length is (1485) cm.The lights transportation ability is about 5.6%. When the length of WLSF is 1.1 m, the bend radius is 20 mm,the photon number N transferred by the fiber meet the demand of SSND. According to the result, BCF-91A type WLSF is a good candidate for SSND.
