Paper Abstract

A scaled version of a scintillating fiber detector using a high-speed CCD camera has been constructed in a feasibility study at SAIC-San Diego for characterization of its response to fast neutrons and to high energy gamma-rays. The detector concept relies on the combination of long, thin plastic fibers and the kinematics of the neutron-proton reaction to provide an effective means to discriminate against background (non-target) neutrons entering at directions non-parallel to the fiber axis. In the present study, the detector was modified to accept a commercially available high-speed CCD camera capable of frame rates up to 850 Hz. We describe here measurements for determining the neutron detection efficiency, directionality, and gamma-ray sensitivity and discuss improvements which were made to enhance the fiber bundle performance.
