19th JUNO International Collaboration Meeting Held Online
The 19th International Collaboration Meeting of the Jiangmen Underground Neutrino Observatory (JUNO) was held online from January 17 to 28. The meeting consisted of three plenary sessions, 31 parallel sessions and technical reviews. About 210 scientists from Asia, Europe, and the Americas attended.
Prof. WANG Yifang, JUNO spokesperson and director of IHEP, summarized progress on the project at the plenary session. He said onsite detector installation began in December just as long-delayed civil construction was almost completed. This year will be crucial for construction of the detector since all kinds of difficulties and challenges remain. He said everyone involved will work together to complete the challenging task on schedule.
HENG Yuekun, Local Installation Manager, reported on onsite organization and work progress. The first two 16-meter high supporting legs of the stainless steel truss have been successfully installed. Onsite work will continue during the Chinese New Year holiday. In addition, relevant supervisors made progress reports on each subsystem. Furthermore, attendees extensively discussed the low background control during the liquid scintillator filling process and the selection of the filling scheme.
The 2021 JUNO Achievement Award for Young Researchers was awarded to CHENG Jie of North China Electric Power University for her “key contributions to the diffuse supernova neutrino background (DSNB) sensitivity studies in JUNO.” The JUNO Ph.D. Thesis Prize was awarded to HAN Yang of the University of Paris and ZHANG Feiyang of Shanghai Jiaotong University.
The next collaboration meeting will be held on July 18-29, 2022.
