Embodiment 1
[0033] A device for integrated storage of laser polarized xenon, comprising a heat preservation chamber 2, a refrigeration unit 1 for cooling the interior of the heat preservation chamber 2, and a control unit 3 for controlling the refrigeration temperature of the refrigeration unit 1,
[0034] Several cold trap units are arranged in the heat preservation chamber 2, and the cold trap unit includes a helical tube 31. One end of the helical tube 31 is connected to the air inlet connector 34 through the inner vacuum sleeve pipe 38, and the other end of the helical tube 31 is connected to the air outlet through the outer pipe 37. The connecting head 35 is connected, the two sides of the spiral tube 31 are provided with permanent magnets for providing a magnetic field, the inner vacuum sleeve pipe 38 is provided with an inlet vacuum valve 33 , and the outer pipe 37 is provided with an air outlet vacuum valve 36 .
[0035] Preferably, the spiral tube 31 is placed vertically, the bott...
Embodiment 2
[0044] Alkali metals use rubidium as an example, the working gas uses a mixed gas of xenon + nitrogen + helium, and the magnetic resonance imaging of human lungs uses laser polarized xenon-129 gas as a contrast agent.
