Abstract
| A high-temperature critical superconductor (HTS) dipole magnet relying on 12-mm REBCO tapes was built at CEA Saclay in 2016. Magnet studies had been started in the framework of the EuCARD High Field Magnet program and continued within a collaboration agreement between CEA-Saclay and CERN. The final goal is to generate 5.4 T at 4.2 K in the 13-T background field of the FRESCA2 Nb$_{3}$Sn dipole magnet. The HTS winding is made of three double-layer racetrack-type coils, wound from a stack of two double-layer REBCO tapes, stabilized with beryllium copper ribbons. Before it is installed inside the aperture of FRESCA2, at CERN, the magnet has been tested at CEA-Saclay in the standalone mode. In this paper, after a brief recall of the magnet design, we will report on the magnet manufacturing and the first powering tests results. |
