ESSnuSB Experiments:
List of ESSνSB / ESSnuSB experimental components
ESSνSB Long-Baseline Neutrino Oscillation Experiment — main proposed experiment to measure leptonic CP violation at the second neutrino oscillation maximum.
ESS Proton Linac Upgrade — high-power proton driver for producing the neutrino beam; proposed upgrade toward 10 MW, 2.5 GeV, 28 Hz operation.
Accumulator Ring — compresses the ESS linac pulse from milliseconds to about 1–1.3 μs for horn focusing.
Target Station — high-power neutrino production target system, typically described with four targets and four magnetic horns.
Magnetic Horn Focusing System — focuses charged pions/kaons to create intense νμ or anti-νμ beams.
Decay Tunnel / Beamline — allows focused mesons to decay into neutrinos before the beam travels to detectors.
ESSνSB Near Detector Complex / END — measures neutrino flux and interaction cross-sections near the source. It includes:
Water Cherenkov near detector
Super Fine-Grained Detector / SFGD
NINJA-like emulsion detector, “Viking”
ESSνSB Far Detector / FD — large underground Water Cherenkov detector, often described as two large tanks with total mass around 540 kt, proposed at a long baseline such as Zinkgruvan mine, ~360 km from ESS.
ESSνSB+ / ESSnuSB-plus — extension program for precision neutrino–nucleus cross-section measurements in the 200–600 MeV region.
Low-Energy nuSTORM / LEnuSTORM — ESSνSB+ facility concept for controlled low-energy neutrino beams.
Low-Energy Monitored Neutrino Beam / LEMNB — ENUBET-like monitored beam concept under ESSνSB+.
Near-Near Water Cherenkov Detector — ESSνSB+ detector concept for cross-section measurements and possible sterile-neutrino studies
