That said - a 120l leak of liquid helium is both stupidly expensive, and highly damaging to the MRI unit: there's a bath of ~1000-1500l of liquid helium in an MRI to keep the superconducting coils at superconducting temperatures. Losing ~10% of that volume probably means the unit won't work
- terramex 8y agoWhen you install a new unit you use additional helium that boils off just to bring it to superconducting temperature.
