Conceptual design of a high-field septum magnet using a superconducting shield and a canted-cosine-theta magnet
/ Barna, Dániel (Wigner RCP, Budapest) ; Novák, Martin (Wigner RCP, Budapest) ; Brunner, Kristóf (CERN) ; Kirby, Glyn (CERN) ; Goddard, Brennan (CERN) ; Borburgh, Jan (CERN) ; Atanasov, Miroslav Georgiev (CERN) ; Sanz Ull, Alejandro (CERN) ; Renner, Elisabeth (CERN) ; Bartmann, Wolfgang (CERN) et al.
A zero-field cooled superconducting shield was previously proposed to realize a high-field (at least 3 T) septum magnet for the Future Circular Collider proton-proton ring. In this paper, we present the conceptual design of a complete septum magnet prototype including a shield with an optimized shape and a simple and cost-effective superconducting magnet using the canted cosine theta concept.

The Superconducting Shield (SuShi) Septum Magnet Prototype
/ Barna, D (Wigner RCP, Budapest ; Miskolc U.) ; Borburgh, J (CERN) ; Atanasov, M (CERN) ; Kirby, G (CERN) ; Giunchi, G (Unlisted, IT) ; Kárpáti, V (Miskolc U.) ; Szűcs, M (Miskolc U.) ; Szabó, G (Miskolc U.) ; Mertinger, V (Miskolc U.)
The Future Circular Collider proton-proton ring would require a high-field septum magnet with a blade as thin as possible for the extraction of the 50 TeV proton beam from the ring. One of the two baseline concepts in the conceptual design report is the “superconducting shield” (nicknamed as SuShi) septum, utilizing a zero field cooled, passive superconducting shield in order to create a zero-field channel for the circulating beam inside the bore of a 3 Tesla canted cosine theta (CCT) type superconducting magnet.

Training-free performance of the wax-impregnated SuShi septum magnet
/ Barna, D (Wigner RCP, Budapest) ; Brunner, K (Wigner RCP, Budapest) ; Novák, M (Wigner RCP, Budapest) ; Borburgh, J (CERN) ; Atanasov, M (CERN) ; Lackner, F (CERN) ; Olvegård, M (Uppsala U.) ; Pepitone, K (Uppsala U.) ; Santiago Kern, R (Uppsala U.) ; Svanberg, C (Uppsala U.) et al.
In the framework of the Future Circular Collider Study a new septum magnet concept, nicknamed ‘SuShi’ has been developed, and a prototype was built at Wigner Research Center for Physics, and tested at the FREIA facility of Uppsala University in April 2023. The concept uses a canted cosine theta (CCT)-like superconducting magnet and a passive superconducting shield to create a zero-field and high-field region within its aperture. [...]

Mechanical Structure for the PSI Canted-Cosine-Theta (CCT) Magnet Program
/ Montenero, Giuseppe (PSI, Villigen) ; Auchmann, Bernhard (CERN) ; Brouwer, Lucas (LBL, Berkeley) ; Calzolaio, Ciro (PSI, Villigen) ; Caspi, Shlomo (LBL, Berkeley) ; Rolando, Gabriella (PSI, Villigen) ; Sanfilippo, Stephane (PSI, Villigen)
Abstract: The Canted-Cosine-Theta (CCT) technology has the potential, by its intrinsic stress-management, to lower coil stresses in high-field accelerator magnets. This is especially relevant for Nb3Sn magnets, which may be subject to irreversible degradation if the coil stresses exceed critical values. [...]

An innovative high-field superconducting magnet of Canted-Cosine-Theta (CCT) type has been proposed for Future Circular Collider 16 T dipole magnet design. The unique mechanical structure intercepts the accumulated forces lowering the stress on the windings, constituting intrinsic stress management in high-field Nb $_{3}$ Sn accelerator magnets. [...]
