Paper Abstract

Chinese Spallation Neutron Source (CSNS) is under construction in Guangdong province since 2008. The investigation of the Neutron Scintillator Detector Arrays (NSDA) have been developed to fulfill the requirements of the General Purpose Power Diffractometer (GPPD). The detector module consists of 6LiF/ZnS (Ag) scintillators, crossed WLSF arrays, multi-anode photo multiplier tubes (MA-PMT), and the ASIC readout electronics. The position resolution of the detector module is 4mm×4mm, and the thermal neutron detect efficiency is better than 45%. 38 detector modules for phase I of the GPPD have been finished and been installed in GPPD in Aug., 2017. Joint debugging with neutron beam in the GPPD was started at the CSNS on November 1, 2017. During the 10-day joint debugging period, the NSDA successfully obtained diffraction data. The instrument resolution of the diffraction data for the standard Si powder for high angle banks is calculated to be 0.184%. It is better than that of the physical design.
