Abstract
Abstract A superconducting magnet comprising a superconducting coil disposed in an insulation housing, a heat insulation support rod for supporting said superconducting coil against a room temperature wall of the insulation housing, a heat insulation plate disposed on a side of the superconducting coil, and a thermal anchor inserted between said insulation rod and said superconducting coil and carrying a cooling pipe to provide a path for a refrigerant carrier to flow through. The heat insulation plate has a higher heat resistance than that of the thermal anchor to reduce the influent heat from the room temperature wall to the superconducting coil so as to improve performance of the superconducting magnet.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
94 words
A superconducting magnet comprising a superconducting coil disposed in an insulation housing, a heat insulation support rod for supporting said superconducting coil against a room temperature wall of the insulation housing, a heat insulation plate disposed on a side of the superconducting coil, and a thermal anchor inserted between said insulation rod and said superconducting coil and carrying a cooling pipe to provide a path for a refrigerant carrier to flow through, whereby influent heat from the room temperature wall to said superconducting coil is substantially reduced to improve performance of said superconducting magnet.
