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 relates to a method for determining the degree of polarization (P) of a nuclear spin polarized gas, in particular 3He, 129Xe, in which the nuclear spin polarized gas is placed in a container, comprising determining the magnetic field Bd of the pola gas by measuring the magnetic dipole field emerging therefrom and then determining from Bd the degree of polarization of the gas.
