5. 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 …
