The main detector of SANS at CSNS

The data are derived from the main detector of the small angle neutron scattering spectrometer of Chnia Spallation Neutron Source , which is a large area 3He tube array detector. The data is generated for calibration of the detector, including position information, charge information and time of flight information, position spectrometer, charge spectrum and time of flight spectrum of neutrons can be obtained. The performance of the detector can be obtained by processing the data, and the position distriution detected by the detector can be calibrated.
