An initiative to design and build magnetic resonance imaging (MRI) and spectroscopy (MRS) instruments at 14 T and beyond to 20 T has been underway since 2012. This initiative has been supported by 22 interested participants from the USA and Europe, of which 15 are authors of this review. Advances in high temperature superconductor materials, advances in(More)
Performance degradation of Nb 3 Sn cable-in-conduit-conductors (CICCs) is a critical issue in large-scale magnet design such as in the International Thermonuclear Experimental Reactor (ITER) and the series-connected hybrid (SCH) magnets currently under development at the National High Magnetic Field Laboratory (NHMFL). The critical current Ic of Nb 3 Sn(More)
—The NHMFL presently has three Series-Connected Hybrid (SCH) projects, two of which are entering a construction phase. The design of the SCH outsert magnets is based on a CICC configuration using cable of multi-filamentary Nb 3 Sn and Cu strands inside a stainless steel jacket cooled by forced flow supercritical helium at 4.5 K. The outsert coil design is(More)
The three goals of this paper are: 1) to evaluate the improvements in technology for increasing magnetic flux density (magnetic field) to 14T in the next few years and eventually to 20T; 2) to highlight neuroscience opportunities enabled by these advances; and, 3) to evaluate the physiological and biophysical effects associated with MRI at very high(More)
—Accurate prediction of the performance of Nb 3 Sn cable-in-conduit-conductors (CICCs) is challenging but critical for the design of high field magnets such as the series connected hybrid (SCH) magnet currently under development at the NHMFL. With various CICC tests performed for EFDA dipole magnet and ITER, we present the Florida electro-mechanical cable(More)
We performed a feasibility study on a high-strength Bi2-x Pb x Sr2Ca2Cu3O10-x (Bi-2223) tape conductor for high-field solenoid applications. The investigated conductor, DI-BSCCO Type HT-XX, is a pre-production version of Type HT-NX, which has recently become available from Sumitomo Electric Industries (SEI). It is based on their DI-BSCCO Type H tape, but(More)
