描述了用于超低能高纯锗探测器实验的数据获取(DAQ)系统,该实验用于对WIMP粒子在质量100GeV/c2以下,特别是低于10GeV/c2范围内的探寻。DAQ系统采用一台四通道数字化示波器,同时读取来自高纯锗探测器和反康普顿谱仪CsI(Tl)晶体探测器的数据。基于ROOT的数据获取程序把数据存为特定的格式。整套系统已稳定运行了数月。随着实验数据的积累,实验运行参数的优化工作即将展开。
Describes a data acquisition (DAQ) system for experiments on ultra-low energy, high-purity germanium detectors that are being used to explore WIMP particles below 100 GeV / c2, and especially below 10 GeV / c2. The DAQ system uses a four-channel digital oscilloscope that reads both CsI (Tl) crystal detectors from a high purity germanium detector and an anti-Compton spectrometer. ROOT-based data acquisition program to save the data in a specific format. The entire system has been stable for several months. With the accumulation of experimental data, optimization of experimental operating parameters is about to start.
