Abstract

See full text

A high magnetic field superconducting magnet system with large crossing warm bore is disclosed, a superconducting coil thereof includes a low temperature superconducting coil and a high temperature superconducting coil. The superconducting coils are connected to a thermal shield and a flange of a low temperature container by a supporting drawbar, thus the superconducting coils as a whole are supported inside the low temperature container. A thermal switch is connected to a primary cold head and a secondary cold head of the cryocooler. The secondary cold head of the cryocooler is connected to a magnet-reinforced supporting flange at the two ends of the low temperature superconducting coil and the high temperature superconducting coil by a cold conduction strip. The 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 used for preventing thermal radiation by the room temperature bore in horizontal direction to the superconducting coils. 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 when the superconducting magnet system is formed as a whole.
