Summary
A long-baseline experiment for CP violation, the neutrino mass ordering and supernova neutrinos. The far detector consists of modules of about 17 kt of liquid argon each, about 1.5 km underground.
Now as of 4 Nov 2026
Underground work is under way: the first steel cryostat is being lowered into the mine. Scientific American reported in May 2026 that delays have added about five years to the schedule, with data taking now expected around 2030 and the total cost approaching 5 billion dollars (summary by Pulse).
