The study of active geomagnetic shielding coils system for JUNO [PDF]

Journal of Instrumentation, 2021
Abstract The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator (LS) detector for neutrino mass ordering and other neutrino physics research. The detector uses large-size 20 inches photomultiplier tubes to detect photons from a liquid scintillator. The large PMTs are sensitive and easily affected such
