Because it's so cold, liquid helium is
used to chill special magnets inside medical scanners.
Because it is an inert gas, helium is
used in applications as varied as arc welding, semiconductor production and thermo-acoustic refrigeration.
Government, helium is
critical in space, defense, and advanced energy systems--there is no substitute if temperatures below minus 429 degrees Fahrenheit are needed.
a blimp which long ago lost its value as a means of cargo transportation, military reconnaissance, or anti-aircraft defence.
However, current demand has exceeded the government's expectations, according to the NAS, and a significant amount of the helium is
being sold outside the United States.
produced as a by-product of natural gas refinement.
In the midst of increasing volatility in the traditional media industry, Helium is
attracting thousands of publishers and connecting them with high quality subject matter experts on a regular basis.
Worldwide demand for helium is
ballooning," says Bureau of Land Management spokesman Hans Smart.
Superfluid helium does not support the formation of bubbles within the target chambers, and more importantly, the small-angle neutron scattering cross-section of superfluid helium is
smaller than normal liquid helium by a factor of 5 [11,12].
Its helium is
sold to Europe, which until 1994 relied almost entirely on the US.

an essential feedstock for numerous industrial, medical, scientific and commercial applications including nuclear power generation, magnetic resonance imaging ('MRI'), industrial fabrication and welding, fundamental sciences and research, fiber optics, space and defence applications, semiconductor manufacturing, and many other applications.
