Abstract: 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.
