According to the CERN-LHC (Large Hadron Collider) reference design, 10-tesla twin-aperture NbTi dipoles will be built with split collars that enclose both apertures. As part of the development program towards an experimental 11.5-tesla Nb$_3$Sn LHC dipole magnet, the mechanical implications of an alternative collar concept have been studied with a finite element analysis [...]

The Comprehensive Research Facility for Fusion Technology (CRAFT) project has been launched in 2019, for developing the essential engineering technologies for Chinese Fusion Engineering Testing Reactor (CFETR). Within this project, a full-size toroidal field (TF) coil will be built as the prototype coil for CFETR. [...]

Transverse-pressure susceptibility of high-$J_c$ RRP and PIT types of Nb$_3$Sn Rutherford cables for accelerator magnets
/ Gao, P (Hefei, Inst. Plasma Phys. ; Twente U., Enschede) ; Dhallé, M (Twente U., Enschede) ; Bordini, B (CERN) ; Ballarino, A (CERN) ; Ten Kate, H H J (Twente U., Enschede)
In the frame of the High-Luminosity Large Hadron Collider construction and Future Circular Collider development program, the magnetic field in the accelerator dipole magnets is being enhanced to 11 T, and 15 T to 16 T level, respectively. Advanced Nb3Sn superconductors with a non-copper critical current density exceeding 2500 A mm$^{−2}$ at 4.2 K and 12 T, are being developed using the Restacked-Rod-Process (RRP) and Powder-In-Tube (PIT) wire technologies.

A new protection system for superconducting magnets called coupling-loss induced quench system (CLIQ) has been recently developed at CERN. Recent tests on Nb-Ti coils have shown that CLIQ is a valid, efficient, and promising method for the protection of high-magnetic-field superconducting magnets. [...]

Modelling V-I Measurements of Nb$_3$Sn Accelerator Magnets With Conductor Degradation

In the framework of the High-Luminosity Large Hadron Collider (HL-LHC) project, 11 T dipole and MQXF quadrupole magnets employing Nb$_3$Sn technology have been tested in short and long test configurations. Nb$_3$Sn magnets are more sensitive than Nb-Ti magnets to a potential degradation of their conductors during production, testing, and cycling operation. At CERN, new diagnostic tools and measurement procedures have been developed to investigate, in detail, the performance of Nb$_3$Sn accelerator type magnets. [...]

Windability Tests of Nb$_3$Sn Rutherford Cables for HL-LHC and FCC

In the framework of the development of high field magnets made of Nb$_3$Sn superconductors for projects like the high luminosity upgrade of the large hadron collider (HL-LHC) and FCC studies, it is necessary to refine the understanding of the winding process and its impact of the overall mechanical integrity of the conductor. The mechanical behavior during winding of the unreacted Rutherford-type Nb$_3$Sn cables has been studied experimentally. [...]
