Design of Data Acquisition Software for CSNS Angle Neutron Spectrometer

According to the data acquisition requirements of China Spallation Neutron Source (CSNS) Small Angle Neutron Spectrometer (SANS), this paper adopts Linux, C++ and open source technology such as Qt and MySQL to develop the SANS DAQ software. The software realized basic DAQ functions such as electronics configuration, run control, data readout, online data processing and storage, status monitor and error alarm, as well as additional functions like Graphic User Interface (GUI), Online Database and Waveform Reconstruction. Test results show that the software is stable, reliable and efficient, meets the requirements of CSNS SANS.
