Abstract :
A two-dimensional scintillation detector comprising of a single screen of flat neutron-sensitive scintillator with wavelength shifting fibers read out was developed. The detector was designed to meet the requirements for the modulated intensity by zero effort spectrometer (MIEZE) to be installed in the J-PARC/MLF. The ZnS/10B2O3 scintillator screen that had 0.2±0.05 mm in thickness was implemented to the detector to minimize the time parallax within the scintillator. The detector design and the detector performances are presented.
