We have developed a ZnS/$$^{10}$$B$$_{2}$$O$$_{3}$$ scintillator that has a high light output with less afterglow for neutron scattering instruments in the J-PARC/MLF. A commercial ZnS/$$^{6}$$LiF scintillator has widely been used for thermal neutron detection and its superior light output with low $$gamma$$ sensitivity has been proven. However its large afterglow followed with a primary emission light gives a limit on a detector count rate. A detector in the J-PARC/MLF should have a capability to cope with higher count rate than ever since the source flux is increasing up to 1 MW (300 kW at present). To address such problem we have developed the ZnS phosphor that exhibited a low after glow. We have also made a neutron-sensitive scintillator in combination with a $$^{10}$$B$$_{2}$$O$$_{3}$$ by sintering method in search of high detector efficiency. The scintillator properties and the detector performances will be shown in the presentation.
