Abstract

Back-n is a back-streaming beam line at China Spallation Neutron Source, which is suitable for measure nuclear data precisely. The readout electronics of the spectrometers at this facility adopts general-propose design method, using high-speed waveform digitizing technology to record the detector output signal accurately. To read out two channels, 1 GSps, 12 bit sample data and control on-board devices, the real-time readout method of high-speed data based on FPGA technology can be considered. The method not only realizes the general requirements of the data upload, but also processes real-time triggers according to experiments via configuration. In addition, due to the flexibility of FPGAs, new experiments or new features can be supported through firmware updates. The test results show that the method is suitable for the high-speed data readout of field digitizing module at Back-n and peak capacity reaches up to 24 Gbps, which meets the requirements of the physical experiment. The field digitizing modules based on this method were installed at Back-n and work normally.
