초록
A high detection efficiency thermal neutron detector based on the 6LiF/ZnS(Ag) scintillation screens,wavelength-shifting fibers (WLSF) and Silicon photomultiplier (SiPM) readout is under development atChina Spallation Neutron Source (CSNS) for the Engineering Material Diffractometer (EMD).A prototypewith a sensitive volume of 180mm 192mm has been built. Signals from SiPMs are processed by the selfdesignApplication Specific Integrated Circuit (ASIC). The performances of this detector prototype are as follows: neutron detection efficiency could reach50.5% at 1 Å, position resolution of 3, the dark count rate <0.1Hz, the maximum count rate >200KHz. Such detector prototype could be an elementary unit for applications in the EMD detector arrays.
