 R2D2, the CEA Graded Nb$_3$Sn Research Racetrack Dipole Demonstrator Magnet / Calvelli, Valerio (IRFU, Saclay) ; Mallon, Philip (LBNL, Berkeley) ; Durante, Maria (IRFU, Saclay) ; Felice, Helene (IRFU, Saclay) ; Rochepault, Etienne (IRFU, Saclay) ; Manil, Pierre (IRFU, Saclay) ; Minier, Gilles (IRFU, Saclay) ; Rifflet, Jean-Michel (IRFU, Saclay) ; Perez, Juan (CERN) As a part of a collaborative effort with CERN on the long road to FCC-hh, CEA is developing a 1.4 m-long single aperture short dipole demonstrator. This Nb$_3$Sn block dipole, named F2D2, is foreseen to produce 15.5 T with a 14% margin at 1.9 K, and will use a shell-based support structure. [...] 2021 - 6 p. - Published in : IEEE Trans. Appl.

 The Future Circular Collider : Its potential and lessons learnt from the LEP and LHC experiments / Myers, Stephen (CERN ; ADAM, Geneva) As researchers seek to learn more about the fundamental nature of our universe, new generations of particle accelerators are now in development in which beams of particles collide ever more precisely and at ever higher energies. Professor Stephen Myers, former Director of Accelerators & Technology at CERN and currently Executive Chair of ADAM SA, identifies both the positive and negative lessons which future projects can learn from previous generations of accelerators. Building on the extraordinary feats of researchers in the past, his findings offer particularly important guidance for one upcoming project: the Future Circular Collider.. 2022 - 2 p. - Published in : 10.32907/ro-129-2503852314 Fulltext: PDF;

 How to increase the physics output per MW.h for FCC-ee? : Parameter optimization for maximum luminosity / Shatilov, D (Novosibirsk, IYF ; CERN) The efficiency of colliders for physics is largely determined by their luminosity, while most of the energy consumed by high-energy e$^+$e$^-$ colliders is proportional to the total beam current. Thus, the energy efficiency is mainly determined by the specific luminosity that needs to be maximized. [...] 2022 - 6 p. - Published in : Eur. Phys. J.

 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.
