为JUNO实验的不同后端电子选项设计通用验证板
Design of a common verification board for different back-end electronics options of the JUNO experiment
摘要:
JUNO天文台是我国正在建设中的一个中基线实验台。一个大的液体闪烁体体积检测从核反应堆发出的反中微子。液体闪烁体探测器装有17000个大型光电倍增管。为了减少背景,增加了两个否决系统。前端电子系统执行模拟信号处理(水下电子),在大约100米的电缆之后,后端电子系统在水外,由DAQ和触发器组成。整个电子系统的主要挑战之一是快速数据链路(250 Mb/s)与100 m以太网电缆上的电力输送相结合。根据DAQ数据量和向水下系统供电的方式,我们考虑了三种不同的选项来连接前端和后端系统。为了以高效和快速的方式测试这三个选项,设计了一个具有不同夹层板接口的公共基板。
英文摘要:
The JUNO observatory is a medium baseline experiment in construction in China. A large liquid scintillator volume detects the antineutrinos issued from nuclear reactors. The liquid scintillator detector is instrumented with 17000 large photomultiplier tubes. Two veto systems are added to reduce the backgrounds. The front-end electronics system performs analog signal processing (the underwater electronics) and after about 100 m cables, the back-end electronics system, outside water, consists of the DAQ and the trigger. One of the main challenges of the whole electronics system is the fast data link (250 Mb/s) combined with the power delivery over 100 m Ethernet cables. Three different options are considered to connect the front-end and the back-end systems, depending on the DAQ data volume and the way to deliver the power to the underwater system. In order to test the three options in an efficient and fast way, a common baseboard with interfaces to different mezzanine boards is designed.
