The EuCARD-2* collaborative programme (2013-2017) is part of the European long term development aimed at exploring magnet technology operating at 16 T to 20 T dipole field for the next CERN collider projects. The collaboration had as a main focus the development of a 10 kA-class superconducting, high current density cable suitable for accelerator magnets, to be tested in small scale coils and...
A next step of energy increase of hadron colliders beyond the LHC requires high-field superconducting magnets capable of providing a dipolar field in the range of 16 T in a 50 mm aperture with accelerator quality. These characteristics could meet the requirements for an upgrade of the LHC to twice the present beam energy (HE-LHC) or for a 100 TeV centre of mass energy Future Circular Collider...
The Nb3Sn block coil dipole magnet FRESCA2 was developed within the framework of a collaboration between CEA Saclay and CERN, in the continuity of the European project EuCARD. With an aperture of 100 mm and a target bore field of 13 T at 10.8 kA, the magnet is aimed at upgrading the FReSCa cable test facility at CERN. The design features four 1.5-m-long double-layer coils wound with a 40...
The 2014 Particle Physics Project Prioritization Panel (P5) Report identified a critical need for transformational high field dipole magnet R&D, focused on improving performance and reducing the cost per T-m. This need was subsequently reiterated in the HEPAP Accelerator R&D subpanel report.
In response, the DOE Office of High Energy Physics has initiated an ambitious program to aggressively...
This paper presents the design, construction and test results of a hybrid dipole magnet built with inner coils made of High Temperature Superconductor (HTS) and outer coils of Low Temperature Superconductor (LTS). This is believed to be the first significant HTS/LTS hybrid R&D dipole magnet to be built and tested. The dipole is based on the common coil design with simple racetrack coils. The...
Dipoles with 15-20 T operating field are required for some designs of future hadron colliders. Such dipoles require the use of high-field superconductors Nb3Sn, Bi-2212, and REBCO. Designs are presented for block-coil dipoles using superconducting cable-in-conduit. This approach conveys several benefits that are important for high-field operation: cable-level stress management; compact,...
