摘要
Purpose The Jiangmen Underground Neutrino Observatory(JUNO)is a multi-purpose underground neutrino experiment.About 1800020-inch photomultipliers(PMTs)are instrumented in the Central Detector to detect the photons,and the signals will be captured by high-speed high-resolution waveform full sampling technique.In addition,about 250003-inch PMTs are also instrumented to capture T/Q Hits information.This work builds a DAQ readout prototype system for JUNO,which can be used to test the full readout chain for 20-inch and 3-inch PMTs.Methods The system is designed to continuously readout the data flow from multiple electronics channels,check the raw data,and finally save them into disk.Meanwhile,the graphical user interface(GUI)provides a real time display of the sampled waveforms.The system is developed with the open source Qt platform.Results The design and performance of the system have been verified in detail,particularly by performance test based on Gigabit Ethernet and 10-Gigabit Ethernet.Conclusion A DAQ readout prototype system has been developed for JUNO,which is successfully applied to electronics testing system in Italy and PMT testing system in Guangdong.
