High-temperature superconducting REBCO coated conductors have strong potential for high-field magnet applications. Significant technology gaps, however, need to be filled before we can fully leverage the conductor capability for future accelerator magnets. The U.S. Magnet Development Program is collaborating with conductor vendors to address this need. We report on the fabrication and test of...
Rare-Earth Barium Copper Oxide (REBCO) coated conductors are an attractive option for application in high-field accelerator magnets due to their high critical field and the convenience of fabrication without heat treatment compared to some other superconductors.
Fermilab plays a vital role in superconducting accelerator magnet R&D under the framework of the U.S. Magnet Development Program....
High Temperature Superconductors (HTS) offer significant potential for very high field dipole. We started the development of REBCO-insulated dipole magnetsin 2010 with EUCARD and EUCARD2 programs. CEA Paris-Saclay then chose to apply the Metal-as-Insulation (MI) REBCO winding, originally developed in the 32.5 T solenoid insert project NOUGAT, the design, fabrication and tests of HTS high field...
The US Magnet Development Program (USMDP) is pursuing hybrid dipole magnet testing with low temperature superconductor (LTS) outserts and high temperature superconductor (HTS) inserts, as an efficient way to characterize HTS magnets at higher fields and stress levels. In this work, we present the test and performance characterization of the first hybrid dipole test at the recently upgraded...
The novel uni-layer concept for superconducting magnets introduces a new geometrical approach to form a magnetic field orthogonal to an aperture. The new design allows for independent single layers, eliminating the need for internal layer jumps and favoring the use of grading, while maintaining high efficiency in the use of conductor. The unique attributes of the uni-layer concept are...
Building on the initial magnetic design of DAISY, the 14 T common coil magnet demonstrator being developed at CIEMAT under the High Field Magnet (HFM) programme, this paper investigates the feasibility of hybrid designs combining Nb₃Sn and NbTi for high- and low-field regions, respectively. The primary goal is to minimise superconductor usage while ensuring that the magnet meets the functional...
A new testing facility employing a 15-T transverse field to evaluate the full-service-field characteristics of superconducting materials is now under development in China. A key objective is the development of a large bore, 15-T dipole magnet to provide the transverse magnetic field load. In this study, we designed and constructed a compact high-temperature superconducting (HTS) dipole magnet...
