A 25 Tesla superconducting magnet for NMR will be fabricated in the Institute of Electrical Engineering, Chinese Academy of Sciences. The magnet consists of HTS insert and LTS outsert with the central field contribution of 10 T and 15 T, respectively. Based on the features of HTS insert with respect to winding geometry and screening current, an electromagnetic design method is proposed. High...
Abstract— EuCARD-2 is a project partly supported by FP7-EuCARD2 n.312453 Commission aiming at exploring accelerator magnet technology for 20 T dipole operating fields. The EuCARD-2 collaboration is liaising with similar programs for high field magnets in the USA and Japan. EuCARD-2 focuses, through the work-package 10 “Future magnets”, on the development of a 10 kA-class superconducting, high...
To date, quite a number of no-insulation (NI) REBCO magnets have been designed and constructed, and all of them successfully generated their target fields. Some magnets experienced a quench at their full fields and survived without damage. The results have shown a potential of the NI REBCO winding technique for high field user magnets. Motivated by the recent progress, a 20 T...
A Bi2212-based rectangular wire approach has been developed, with up to 500 MPa stress tolerances and useful current densities for building compact solenoid coils that are more problematic to make with wide HTS tapes, and that need to operate beyond the field and temperature limits of low temperature superconductors. We are applying long lengths of this new Bi2212-wire to develop a practical...
One major goal at the NHMFL is the development of high field NMR quality magnets beyond 1 GHz using high temperature superconductors (HTS). Since Bi-2212 is very versatile and can be made in the much more desirable isotropic, round wire, twisted multifilament architecture, it appears to be particularly valuable for high field NMR magnets. We are in the process of building a layer-wound,...
We have succeeded in the development of the 25T cryogen-free superconducting magnet recently [1]. As a next step, a development of 30 T class superconducting magnet is planned. In order to realize high field superconducting magnets beyond 30 T, the reliability of REBa2Cu3Oy (RE123, RE: Y and rare earth) conductors should be improved. For this purpose, we made single pancake coils by co-winding...
High Temperature Superconductors (HTS) are a strong candidate for high field magnets. As their properties are extraordinary especially under high fields and very low temperatures, there are many ongoing projects around the world. The NOUGAT project aims at building a 10 T insert working first inside a 20 T resistive background. Its objectives are not to reach higher field than the already...
