摘要
A neutron scintillating detector and its data taking system have been developed for neutron scattering measurement. A 64-channel flatpanel photomultiplier is used for the Anger-camera method. The detection efficiency of gamma-ray background is very low in the use of the ZnS/(LiF)-Li-6 scintillator. The spatial resolution is less than 1 mm. The effective area of this detector is around 25 cm(2), and it is easy to expand it to a larger area with small dead space using the multi-photomultiplier tubes system. The fast DAQ system has 10-bit 100 MHz flash ADCs, FPGA chips and USB2.0 device. (c) 2006 Elsevier B.V. All rights reserved.
