A two-dimensional scintillation-based neutron detector with wavelength-shifting (WLS) fibers was developed that incorporated a novel data interpolation method. The interpolation method, which was developed for a photon-counting detector, produced an effective pixel size smaller than the physical pitch of the WLS fibers in the array. The WLS-fibers array was constructed by placing fibers at a regular pitch of 2.5 mm in both the x and y directions. The two crossed fiber arrays were sandwiched with two scintillator screens. Detectors with half- and quarter-pitch calculation logics exhibited spatial resolutions of 2.7 +/- 0.1 and 2.5 +/- 0.1 mm, respectively, for the full width at half maximum (for a 1-mm beam width). The corresponding effective pixel sizes were 1.25 and 0.625 mm. The measured spatial resolutions were approximately 1.3-fold better than that with the standard-pitch calculation logic. The presented results demonstrate the feasibility of using the developed interpolation method with a collimated neutron beam. (C) 2014 Elsevier B.V. All rights reserved.
