Abstract:
     The invention discloses a laser polarized 129Xe solid memory, composed of lift table, Dewar, dual circle permanent magnet, iron sleeve, liquid nitrogen, glass casing pipe, two safety vacuum valves and regulating frame, where the dual permanent magnet is set on the iron sleeve with adjustable length to adjust magnetic field strength; there is silicon coat on the inner wall of the glass casing pipe, which is used as its storage room and sample mixing room; the lift table goes up and down to change the temperature of laser polarized 129Xe. It has the advantages of adjustable magnetic field strength, small memory volume, convenient storage and transport, etc. It is mainly applied to magnetic resonance imaging, polarization transfer, medium- and micro- aperture measurement and structure research, enhancement of NMP signal on material surface, etc.
