“…The successful demonstration of the C1 magnet clearly indicated that the CCT concept with round CORC R wires is feasible for HTS accelerator magnets. It is a first step toward practical and reliable HTS magnets as a new paradigm for superconducting accelerator magnet technology that will enable next-generation circular colliders at the energy frontier and stand-alone magnets for applications such as injection chain [33], high radiation environment [34] and ion beam therapy [17,35].…”

REBa 2 Cu 3 O x (REBCO, RE = rare earth elements) coated conductors can carry high current in high background fields, in principle enabling dipole magnetic fields beyond 20 T. Although model accelerator magnets wound with single REBCO tapes have been successfully demonstrated, magnet technology based on high-current REBCO cables for high-field accelerator magnet applications has yet to be established. We developed a two-layer canted cos θ dipole magnet with an aperture of 70 mm using 30 m long commercial Conductor on Round Core (CORC R) wires. The 3.1 mm diameter CORC R wire contained 16 commercial REBCO tapes with a 30-µm thick substrate. The magnet was tested at 77 and 4.2 K. It generated a peak dipole field of 1.2 T with 4.8 kA at 4.2 K with neither thermal runaway nor training. Reasonable geometric field quality and strong magnetization-current effects with multipole decay were observed. Our work demonstrated a feasible high-temperature superconducting magnet technology as a first step toward a new accelerator magnet paradigm that will enable high-field inserts for next-generation circular colliders and stand-alone magnets that can operate over a wide temperature range for a broad range of applications.

“…As shown by increasing number of works on special doping aiming at 4.2 K application [26], [27], this area, that has seen much less effort that the 77 K oriented applications (power engineering), is at present getting much more attention. This is already a positive result of the EuCARD/EuCARD2 program, as well as of other programs for high fields magnets [28]- [31] and Fusion-DEMO [32].…”

Abstract-EuCARD-2 is a project supported by FP7-European Commission that includes, inter alia, a work-package (WP10) called "Future Magnets". This project is part of the long term development that CERN is launching to explore magnet technology at 16 T to 20 T dipole operating field, within the scope of a study on Future Circular Colliders. The EuCARD2 collaboration is closely liaising with similar programs for high field accelerator magnets in the USA and Japan. The main focus of EuCARD2 WP10 is the development of a 10 kA-class superconducting, high current density cable suitable for accelerator magnets, The cable will be used to wind a stand-alone magnet 500 mm long and with an aperture of 40 mm. This magnet should yield 5 T, when stand-alone, and will enable to reach a 15 to 18 T dipole field by placing it in a large bore background dipole of 12-15 T. REBCO based Roebel cables is the baseline. Various magnet configurations with HTS tapes are under investigation and also use of Bi-2212 round wire based cables is considered. The paper presents the structure of the collaboration and describes the main choices made in the first year of the program, which has a breadth of five to six years of which four are covered by the FP7 frame.

“…E have been studying the feasibility of applications of high-Tc superconductors to the magnets for fixed field alternating-gradient (FFAG) accelerators [1], [2]. FFAG accelerators, in which strong focusing can be obtained by the fixed (dc) magnetic field [3], are attractive from the viewpoint of the compatibility with superconducting magnets [4]- [6].…”

We designed a coil-dominated magnet wound with coated conductors for a spiral sector fixed field alternatinggradient (FFAG) accelerator for carbon cancer therapy. The magnet consisted of deformed pancake coils with negative bends. Coils were arranged like a ladder in order to generate the required radial profile of magnetic field. The positions and the number of the turns of the coils were adjusted iteratively to reduce the magnetic field error. We carried out numerical electromagnetic field analyses of the designed magnet to evaluate the influence of the coated-conductor magnetization (screening or shielding current) on its field quality.
