摘要： An open type nuclear magnetic resonance magnet system having an iron ring member. A superconducting coil and a superconducting switch form a closed-loop current circuit to generate a magnetic field. The generated magnetic field gains a magnetic flux circuit and executes magnetic field shielding through upper and lower iron yokes and a lateral iron yoke. The magnet system generates a desired magnetic field in a magnet imaging central area via the superconducting coil. To balance the extremely high electromagnetic force between the superconducting coil and the upper and lower iron yokes, an annular iron ring is mounted in a space defined by an inner perimeter wall of in a cryogenic container. The magnetic field distribution between the superconducting coil and the upper and lower iron yokes is changed via the iron ring, so that the electromagnetic interaction force therebetween is reduced.

摘要： 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.

摘要： A superconducting magnet system for generating high homogeneity and high magnetic field consists of a main coil, an outer coil, a quench protection circuit, a quench heater and a power supply. The main coil is composed of many concentric solenoid coils which are arranged from inside to outside. The outer coil out of the main coil includes a first back roll coil, a second back roll coil, a first superconducting coil for compensating sixth harmonic component, a second superconducting coil for compensating sixth harmonic component, a shielding ring and a shielding coil from inside to outside. Every loop circuit of the quench protection circuit is composed of a corresponding protection resistor, a diode and coil which is connected in series each other, and each coil has a corresponding quench protection heater. The classification linear diameter difference of the superconducting coils which contact each other in main coil is less than 0.05 mm. The homogeneity of the magnetic field in the 50 mm diameter working space is 0.15 ppm, because the high order harmonic component of the field is compensated by back roll method.
