Beschreibung
Zusammenfassung:	The invention discloses a double-channel liquid helium infusion tube which comprises a vacuum outer tube, infusion connectors are arranged at the two ends of the vacuum outer tube respectively, the double-channel liquid helium infusion tube further comprises a liquid helium conveying pipeline and a helium gas return pipeline which are arranged in the vacuum outer tube, the liquid helium conveying pipeline is used for conveying liquid helium, gas gasified after the liquid helium passes through a testing device forms helium gas, and the helium gas return pipeline is used for returning the helium gas to the vacuum outer tube. The helium return pipeline is used for conveying helium, the helium return pipeline and one section of the liquid helium conveying pipeline are arranged in parallel and are in coupling connection through a cold conduction connecting piece, and a heat insulation supporting structure is arranged among the liquid helium conveying pipeline, the helium return pipeline and the vacuum outer pipe.
