Design Blueprint: A Twenty-Kilotonne Liquid Scintillator Detector: Energy Resolution and Reactor-Antineutrino Statistics Computed from Light Yield

Design blueprint derived from the source paper (DOI 10.5281/zenodo.24150276): A spherical liquid scintillator neutrino detector of 20 kilotonnes is designed around one quantity: its light yield. At 1,200 photoelectrons per MeV, collected by 14,934 photomultipliers at 75 percent coverage of a vessel of radius 17.6 m, the computed energy resolution is 3.06 percent at 1 MeV, 1.94 percent at 3 MeV and 3.69 percent at 662 keV, including a stated 1 percent constant term. At a 53 Status: DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. All numbers are simulated values from the source paper's computation, deposited with this blueprint as compute.py and results.json.
