Abstract: Element suitable for motion under ultra-high vacuum conditions, especially a compressor or valve for apparatus for producing polarized gases, includes at least one component moveable in a housing, where the component is moved from an outer space via an intermediate space to an inner space in a way that ingress of volatiles from the outer chamber to the inner space is prevented by sealing rings. Independent claims are included for: (a) apparatus for producing nuclear spin polarized media, including a device for optical pumping in a low pressure plasma, a compressor for the polarized medium and a storage volume, where the compressor includes at least one element as above; and (b) a method for producing nuclear spin polarized gases, involving optical pumping in low pressure plasma, mechanical compression of the gas and supply to a storage volume, where fractional pumping is used for the mechanical compression.

Abstract: The invention provides a magnetically shielded container (1) having disposed in parallel opposed position on an axis (S) thereof magnetic field homogenizing pole shoes (10.1, 10.2), having disposed about said pole shoes a magnetically shielded yoke (2), said pole shoes and yoke enclosing a magnetic chamber (26), said container further comprising magnetic field sources (2.4, 2.5) disposed about and radially distanced from said axis whereby there exists within said chamber substantially homogenous magnetic field Bo oriented in the direction of said axis and whereby there is a usable volume within said chamber where the ratio of the magnetic field gradient in the direction transverse to said axis to said magnetic field Bo has a value of no more than 1.5 x 10 /cm. By virtue of the very low ratio of weight to volume that is achievable with this construction, the containers according to the invention are economical to produce and especially suited to transporting polarized gasses.
