Abstract

A scaled version of a scintillating fiber detector (SFD) has been constructed and tested in a feasibility study at SAIC-San Diego for determining its neutron detection efficiency, directionality and gamma-ray sensitivity. This concept was supported by Monte Carlo simulations which predicted the effectiveness of the fiber bundle to discriminate against neutrons entering at directions non-parallel to the fiber axis. Fibers measuring 0.5 mm square and 10 cm long are formed into a bundle and coupled to a set of gamma-ray insensitive electro-optics intensifiers and a CCD camera. In this paper we describe the detector and present the results of the experimental tests with 14 MeV neutrons and an intense beam of ⁶⁰Co and ¹³⁷Cs gamma-rays.
