It uses liquid nitrogen as coolant. It possesses the advantages of low manufacture, operation and maintenance cost and easy to popularize.
Description
The present invention relates to a kind of high temperature superconductor coil and magnetic resonance device thereof.
Existing superconducting coil and magnetic resonance device thereof all are low temperature, only just have superconductivity under low-temperature condition; So, must use expensive liquid helium as cooling agent, also must adopt complicated secondary cooling system.Operation and service equipment complexity, expense are high, are unfavorable for promoting, popularizing use, especially are unfavorable for applying in the human daily life.
At above problem, the purpose of this invention is to provide simple and lower high temperature superconductor coil and the magnetic resonance device thereof of expense of a kind of operation and service equipment.Have and to use economical and practical liquid nitrogen, can adopt simple and practical liquid nitrogen cooling system, greatly reduce manufacturing cost, operation and maintenance cost, be convenient to promote, popularize and use, help applying in the human daily life as cooling agent.
The objective of the invention is by adopting the high-temperature superconductor bi tape to realize, the conductor that promptly adopts the high-temperature superconductor bi tape to make is realized.
A kind of high temperature superconductor coil is characterized in that: the lead of coil is made with the high-temperature superconductor bi tape.
A kind of high-temperature superconductor magnetic resonance device comprises field coil and cooling system, it is characterized in that: the conductor in the field coil all adopts the high-temperature superconductor bi tape to make.
Describe in detail below in conjunction with embodiment:
Embodiment one
A kind of high temperature superconductor coil, the lead made from high-temperature superconductor (Bi-2223) material are wound on the master that makes with fiberglass, pay on the coil rack.Because of (Bi-2223) high-temperature superconductor bi tape can be realized superconduction in Kelvin 77 degree, the coil of the lead coiling made from this material can be in the superconduction operating state in Kelvin 77 is spent.So, can use economical and practical liquid nitrogen as cooling agent, can adopt simple and practical liquid nitrogen cooling system.Obviously, this coil can be widely used in the high-temperature superconductor equipment miscellaneous.
Embodiment two
A kind of medical Spectrum Analysis type high-temperature superconductor magnetic resonance device, the conductor in its field coil all uses high-temperature superconductor (Bi-2223) material to make.Can superconduction in Kelvin 77 degree because of (Bi-2223) high-temperature superconductor bi tape, the conductor made from this material can be in the superconduction operating state in Kelvin 77 is spent; So, can use economical and practical liquid nitrogen as cooling agent, can adopt simple and practical liquid nitrogen cooling system.Because of in field coil, having adopted the lead made from the high-temperature superconductor bi tape to be wound on the coil rack that fiberglass makes; So coil can be worked in the temperature of Kelvin 77 degree, can produce the required magnetic field less than the 0.1ppm uniformity in the spherical volume zone of 40-45 cm diameter.
Embodiment three
A kind of medical image display type high-temperature superconductor magnetic resonance device, the conductor in its field coil all use high-temperature superconductor (Bi-2223) material to make.Can superconduction in Kelvin 77 degree because of (Bi-2223) high-temperature superconductor bi tape, the conductor made from this material can be in the superconduction operating state in Kelvin 77 is spent; So, can use economical and practical liquid nitrogen as cooling agent, can adopt simple and practical liquid nitrogen cooling system.Because of in field coil, having adopted the lead made from the high-temperature superconductor bi tape to be wound on the coil rack that fiberglass makes; So coil can be worked in the temperature of Kelvin 77 degree, can produce the magnetic field of required 5～20ppm uniformity in the spherical volume zone of 40-45 cm diameter.
Obviously, high-temperature superconductor magnetic resonance device of the present invention can be an image display type high-temperature superconductor magnetic resonance device, also Spectrum Analysis type high-temperature superconductor magnetic resonance device, or the high-temperature superconductor magnetic resonance device of other types.
