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 ...

Liquid helium has a temperature of 1 kelvin (−272 °C) in the vacuum conditions in space, and as it absorbs heat it boils to release helium gas. SHI have developed several compact Dewars that ...

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 ...

However, low-temperature superconductivity materials, which are commonly used in society, require expensive liquid helium as coolant. This represents an obstacle to the popularization of ...

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 ...

“The applications, they’re a little bit sexier than filling party balloons. Liquid helium is the coldest substance on the planet and it’s used as the refrigerant for the super-conducting ...
