Abstract

For evaluating neutron optical devices, we have designed and tested two-dimensional position-sensitive neutron detectors (PSND) which employ two wavelength-shifting fiber arrays optically coupled to a scintillator plate. Feasibility on applications of the PSND having a 50 × 50mm2 sensitive area and a pixel size of 0.4 × 0.4 mm2 has been tested at pulsed neutron sources. While, for realizing the large sensitive area, another PSND having a 128 × 128 mm2 sensitive area and a 0.5 × 0.5 mm2 pixel size with a dynode coding technique were developed and tested.
