A superconducting magnet system and a cyclotron using the same. The superconducting magnet system includes a cryogenic device, a superconducting device and a protecting module. The cryogenic device includes a refrigerating machine and a cryogenic container assembly. The cryogenic container assembly includes a first container end, a connecting tube and a second container end. The first container end is communicated with the second container end through the connecting tube. The superconducting device includes a superconducting coil arranged in the first container end and immersed in a liquid or gaseous cooling medium. The protecting module is connected to the superconducting coil and is configured to protect the superconducting coil if the superconducting coil suffers a quench.

Superconducting magnet system for cyclotron and cyclotron comprising ihe same

Disclosed a quench protection device of a superconducting magnet system, including a superconducting coil set; the superconducting coil set comprises two superconducting coils () which are symmetrical arranged, and each of the two superconducting coils () is connected in parallel with a protection diode (); the superconducting coils and the protection diode are connected with the power supply via a conductive wire; the superconducting coils set are connected in parallel with a quench protection unit (), a change-over switch () is arranged on a circuit of the two superconducting coils, the protection diode, and the power supply, and the change-over switch () is connected with an external resistor via a conductive wire (). The change-over switch of the quench protection device connects the superconducting coil and an external resistance, which realizes the quench protection of the superconducting coil.
