Description
Summary:The Jiangmen Underground Neutrino Observatory (JUNO) is a medium baseline reactor neutrino experiment under construction in Kaiping, Jiangmen, in Southern China. The main detector consists of a transparent sphere containing 20,000 tons of liquid scintillator, surrounded by approximately 17,000 photomultiplier tubes. The information delivered by 20 PMT stations is digitized continuously and aggregated at the RMU level. The main RMU task is to provide 20 input optical links at 0.5 Gbps and 1 optical output running at 10 Gbps. A White Rabbit controller is implemented on the the RMU in order to synchronize all links and to guarantee fixed latency traffic. In this contribution we describe the full RMU hardware and software architecture.
