A two-dimensional neutron detector with a spatial resolution of 200 um was developed for neutron diffraction imaging at J-PARC MLF. The detector was designed by using a thin scintillator screen and wavelength shifting fibers to fulfill the requirement for our demonstrative diffraction experiment planed in the MLF. In this paper design and experimental results of the developed detector are presented.

We have developed a time-of-flight neutron imager based on the two-dimensional scintillator neutron detector technology for applications in the J-PARC/MLF. The detector is comprised of a thin ZnS scintillator with crossed wavelength-shifting-fibers arrays equipped with the fiber optic taper. The developed detector based on a neutron counting method has a high spatial resolution of less than 100 um in full width at half maximum with a -ray sensitivity of less than 1010. The detector design and basic detector performances are presented.
