In physics and a major breakthrough in the discovery of a large high field superconducting magnet apparatus research

Chinese Academy of Sciences, hefei institute of material science researchers in strong magnetic field science center for large high field superconducting magnet on hybrid magnet unit implements the design index of the 100000 gauss, 400000 of gaussian mixture magnet alignment success laid the foundation to a key. The national '11th five-year plan' major science and technology infrastructure - — Steady magnetic field experiment project including the device to generate 400000 gauss magnetic field of the hybrid magnet, it is composed of diameter is 920 mm 100000 gauss superconducting magnets and contain them 300000 gauss water-cooled magnet, the water-cooled magnet has been successfully implemented in separate test in September. Due to the high cost, large diameter high field superconducting magnet is difficult, high risk and long development period, become one of the key technology of hybrid magnet development success. The success of the superconducting magnet is a new milestone in the development of superconducting technology international, after there is no such a large magnet in the world can produce 100000 gauss magnetic field, nor can produce 100000 gauss magnetic field of the superconducting magnet can reach such a large caliber. As a result, it not only set up a successful development of our country high steady state scientific research of strong magnetic fields by platform, also for the development of international high field superconducting magnet technology creates new successful experience. Large high field superconducting magnet device is a complicated system engineering, it not only need the magnet itself has a good electromagnetic performance and mechanical performance, success also need helium cryogenic cooling system, superconducting magnet power supply, security and control system of multiple subsystems such as close cooperation and security. As a result, the superconducting magnet debugging success, is also the success of independent research and development of the related subsystem test. It is understood that the steady magnetic field to physics, materials, chemistry, life science and other multi-disciplinary cutting-edge research provides a rare extreme experimental conditions, therefore, developed, including high field superconducting magnet, strong magnetic field experiment device for promoting science development is of great significance in our country; Not only that, large high field superconducting magnet technology also has other important application prospect. Will be based on the existing strong magnetic field center, strive for an early 400000 alignment, the gaussian mixture magnet device constantly climbing technique and scientific research of strong magnetic fields by a new peak.
