COLLOQUIUM: Large Scale Superconducting Magnets for Variety of Applications

Professor Joseph Minervini
Massachusetts Institute of Technology

Over the past several decades the U. S. magnetic confinement fusion program, working in collaboration with international partners, has developed superconductor and superconducting magnet technology to a very advanced level. These developments have been made using the low temperature superconductors (LTS) NbTi and Nb3Sn. The now operating Large Hadron Collider at CERN has demonstrated the scientific success of NbTi technology on a very large scale. In the future, Nb3Sn and NbTi conductor and coil technology will be demonstrated in the Cable-In-Conduit-Conductor (CICC) configuration in the ITER tokamak. These conductors will be operated in both the dc and pulsed mode. Now that ITER is well into the construction phase, fusion magnet researchers are turning their attention to a Fusion Nuclear Science Facility (FNSF), and beyond, to a DEMO fusion reactor. Since ITER is being built with 1990’s technology, we believe a DEMO reactor design, eventually leading to a commercial reactor, would use some form of High Temperature Superconductors (HTS). Our fusion magnet research is focused on developing HTS conductors for high current operation (50 kA - 100 kA) at very high field (15 T - 22 T) in fusion devices. The use of this technology, operating at temperatures much higher than 4.2K, could allow for magnets with demountable joints, leading to improved machine maintainability. In this talk, I will describe the state-of-the-art and future directions for conductor and magnet technology for fusion applications Superconductors, however, have many applications well beyond magnetic confinement fusion and high energy physics devices. They are being used in very advanced applications for basic science research and in applications for medicine, electric power grid, and security applications. A brief overview and some examples of these applications will also be presented.
