Patent ID: 8570127

Claim:
A high magnetic field superconducting magnet system with large crossing warm bore, comprising: a cryocooler, a low temperature container, a superconducting coil, a thermal switch, a cold conduction strip, and a current lead, wherein said cryocooler is fixed on a flange of the low temperature container, a primary cold head of the cryocooler cools a thermal shield of the low temperature container and a secondary cold head of the cryocooler cools a low temperature superconducting coil and a high temperature superconducting coil, characterized in that, said superconducting magnet system has a room temperature bore in horizontal direction and a room temperature bore in vertical direction; a thermal shield outside the room temperature bore in horizontal direction is coaxially arranged at the periphery of the room temperature bore in horizontal direction and is used for preventing thermal radiation by the room temperature bore in horizontal direction to the low temperature superconducting coil and the high temperature superconducting coil; a separation supporting frame separates the low temperature superconducting coil and the high temperature superconducting coil into two parts, such that a two-dimensional room temperature space can be included inside the superconducting magnet system when the superconducting magnet system is formed as a whole.
