MANUFACTURING DEVICE FOR SPIN POLARIZATION GAS, AND INSTRUMENT AND METHOD FOR MEASURING DEGREE OF POLARIZATION IN SPIN POLARIZATION GAS

摘要

PPROBLEM TO BE SOLVED: To provide a manufacturing device for spin polarization gas, and an instrument and method therefor, which quantitatively and easily measure a degree of polarization of manufactured spin polarization gas, and to restrain the degree of polarization from being reduced by the measurement. PSOLUTION: This device/instrument/method has a spin polarization gas manufacturing part 2 for impressing a magnetostatic field to a rawSP129/SPXe gas GS1 and rubidium in a storage cell 5, and for emitting an excitation light to prepare aSP129/SPXe gas GS2 of a spin polarized condition, a piping 15 for guiding theSP129/SPXe gas GS2 from the manufacturing part 2 to an area distant therefrom, a coil 20 for an inclined magnetic field for impressing the inclined magnetic field, An RF transmission coil 22 for impressing a rotational magnetic field, and an RF reception coil 24 for detecting a nuclear magnetic resonance signal from theSP129/SPXe gas GS2. The nuclear magnetic resonance signal is detected by the reception coil 24 when operating the coil 20 for the inclined magnetic field and the transmission coil 22 to make a flow velocity of theSP129/SPXe gas GS2, an intensity variation rate in a magnetic field of the inclined magnetic field and magnetic field intensity of the rotational magnetic field satisfy a heat insulation excitation condition.
