The non-thermal gaseous plasma may be formed of helium or a mixture of helium and oxygen.

The gas of such cell is comprised of a mixture of helium-3 and helium-4.

A system and method for recovering helium-3 from helium.

hydrogen desorbed by the helium stream

A helium separation junction is provided for separating helium gases entrained in aqueous fluids.

This helium shortage will affect a wide range of helium applications.

Helium flow exhausts from the separator vertically.

A helium leak detection device for detecting helium leak in a steel barrel (5) is disclosed.

The clusters contain coherent helium particles.

This invention is directed to a process for recovering helium.

Besides, inventions help to increase helium extraction rate (97.0 percent) and decrease the cost of pure helium production.

A modular architecture for helium compressors is described.

The gaseous top stream includes an enhanced concentration of helium.

The hydrostatic gas bearing is provided with a gas ejecting equipments composed of a cylindrical fine hole having a diameter of not less than 0.04 mm and not more than 0.4 mm, wherein a helium gas is ejected through the cylindrical fine hole.

The plant further includes a helium inventory control system which includes a plurality of helium storage tanks whereby helium can be fed into or removed from the power generation circuit.
