Calibration of JUNO detector• Important to reach 3% @ 1 MeV energy resolution• Important to reach sub-1% absolute energy scale• Calibrate the PMT timing pulse-shape
discrimination ability of JUNO• Synergies with DYB/PROSPECT: – Energy model is important to extract neutrino spectrum crucial for JUNO, as no near detector
• Ideas: positron sources, B12, diffused beta or positron sources, neutron sources, electron/positron pelletrons …
• Also high performance LS R&D …
