Helium free MRI scanners sidestep a global problem
To achieve this, the magnets are immersed in around 2,000 litres of liquid helium ... “Managing helium supply and ensuring that the system remains at the required temperature can be complex ...

Ultra-Low Temperature ‘Wet’ Helium-3 Cryostats
The Helium-3 systems with incorporated magnets offer temperatures of 0.280 K, with a range of samples in vacuum (on a cold-finger), or submerged in a liquid He-3 system. They are delivered with ...

Cook Up Your Own High-Temperature Superconductors
Superconductors that can work at the relatively high temperature of liquid nitrogen instead of ultracold liquid helium are pretty easy to come by commercially, so if you’re looking to just float ...
