A 4-T, 10-m free bore and 20-m long central solenoid is proposed as the main magnet in the baseline detector for the future circular collider (FCC) hadron–hadron collisions physics program. Besides the 4-T axial magnetic field around the interaction point in the center of the main solenoid, additionally, magnetic field is required in the forward directions. [...]

As part of the LHC accelerator research program (LARP), three US national laboratories (BNL, FNAL, and LBNL) are currently engaged in the development of superconducting magnets for the LHC interaction regions (IR) beyond the current design. As a first step towards the development of long Nb3Sn quadrupole magnets, a 3.6 m long structure, based on the LBNL subscale common-coil magnet design, will be fabricated, assembled, and tested with aluminum-plate "dummy coils".

Test Results of LARP 3.6 m ${\rm Nb}_{3}{\rm Sn}$ Racetrack Coils Supported by Full-Length and Segmented Shell Structures

As part of the LHC Accelerator Research Program (LARP) to build a high performance quadrupole magnet with Nb$_3$Sn conductor, a pair of 3.6 m-long Nb$_3$Sn racetrack coils has been made at Brookhaven National Laboratory (BNL) and installed in two shell-type support structures built by Lawrence Berkeley National Laboratory (LBL). These magnet assemblies have been tested at 4.5 K at BNL to gauge the effect of extended length and prestress on the mechanical performance of the long structure compared to earlier short models.

Test results of TQS03: A LARP shell-based Nb$_3$Sn quadrupole using 108/127 conductor

Future insertion quadrupoles with large apertures and high gradients will be required for the Phase II luminosity upgrade (10$^{35}$ cm$^{−2}$s$^{−1}$) of the Large Hadron Collider (LHC). Although improved designs, based on NbTi, are being considered as an intermediate step for the Phase I upgrade, the Nb$_3$Sn conductor is presently the best option that meets the ultimate performance goals for both operating field and temperature margin.

Exploring cosmic origins with CORE: Survey requirements and mission design
/ CORE Collaboration
Future observations of cosmic microwave background (CMB) polarisation have the potential to answer some of the most fundamental questions of modern physics and cosmology. In this paper, we list the requirements for a future CMB polarisation survey addressing these scientific objectives, and discuss the design drivers of the CORE space mission proposed to ESA in answer to the "M5" call for a medium-sized mission.
