As part of the High Field Magnet program (HFM) at CERN, the Nb3Sn block coil configuration is a candidate for the main dipole in future large hadron collider as FCC-hh. To reduce the cost, the use of material grading in the block coil is explored by using NbTi conductor instead of Nb3Sn in the external low field regions. Different designs are being investigated for dipoles with a target...
The Oak Ridge National Laboratory STS Project will enhance the Spallation Neutron Source by adding a new neutron source. The upgrade includes a 30% increase in beam energy and a 50% boost in beam current, doubling the accelerator's power capability to 2.8 MW. The Ring-to-Second-Target Beam Transport (RTST) system is vital in directing high-energy proton beams to the target. A key element of...
There are 96 combined function magnets (48 focusing and 48 defocusing) that have been in operation in the Fermi National Laboratory’s Booster without a critical failure requiring replacement for over 50 years. The Proton Improvement Plan-II (PIP-II) poses risk to these magnets and Fermilab does not currently have the tooling or knowledge of process to fabricate spares. A longer straight...
A new eddy current septum for the fast extraction from CERN’s Proton Synchrotron has been designed and constructed. This development aims to improve the magnet's reliability, extend its service interval, and reduce radiation exposure for maintenance personnel. The new eddy current device is set to replace the existing direct-drive magnet and its ageing power converter.
This paper summarizes...
We present progress in the design and fabrication of CCT6, a Canted Cosine Theta (CCT) Nb3Sn magnet considered as part of the general R&D program for high field superconducting magnets supported by the US Magnet Development Program (US-MDP). Future testing with HTS inserts in a hybrid configuration motivates the design’s large clear aperture of 120 mm and target operating dipole field of 12-14...
The Interaction Regions (IR) for the FCC-ee collider as envisioned by the CERN FCC Feasibility Study requires a variety of superconducting correction coils that must be integrated with the main IR focusing quadrupoles. The present technological basis for these main quadrupoles is to wind superconductor supported in side-by-side slotted tubes, located deep inside the experimental detector...
The report will explore the societal context of the major turning points in the application of superconductivity that have been crucial for the development of magnet technology. This is relevant in that we are now at a point where a further breakthrough is necessary to enable the development of affordable high field magnets (16 to 20 tesla dipoles), appropriate for series production and...
