Because it is totally unreactive, Helium is used to provide an inert protective atmosphere for manufacturing, Semi-Conductors, Fibre optics and Arc Welding.
Given its unique inert and unreactive nature along with its cooling ability, with a boiling point of minus – 268.9 degrees Celsius, it is used in a host of other areas.
- MRI (Largest consumer of Helium 22% global demand)
- The Hadron Collider. (Cern Switzerland) https://home.cern/resources/faqs/facts-and-figures-about-lhc
- Satellite instruments
- NMR spectrometers
- Space Vehicles to cool Liquid Oxygen & Hydrogen (Apollo Mission)
- Pressurising rocket fuel tanks (helium being inert wont mix with any other gases)
- NASA a huge user of Helium. Also SpaceX
- Decorative Balloons
- Weather Balloons
- Airship lifting
- Deep Diving
- Vehicle Airbags (rapid inflation)
- Leak Detection Devices
- All Major Defence equipment
- New Technologies Coming.
- Quantum Computers
- Fusion Reactors
Synchrotrons use electricity to produce intense beams of light more than a million times brighter than the sun. The light is produced when high-energy electrons are forced to travel in a circular orbit inside the synchrotron tunnels by the ‘synchronised’ application of strong magnetic fields.
There is just one in Australia, Melbourne https://www.ansto.gov.au/research/facilities/australian-synchrotron/overview
