Electron-Hadron Colliders: EIC, LHeC and FCC-eh
/ Brüning, Oliver (CERN) ; Seryi, Andrei (Jefferson Lab) ; Verdú-Andrés, Silvia (Brookhaven)
Electron-hadron colliders are the ultimate tool for high-precision quantum chromodynamics studies and provide the ultimate microscope for probing the internal structure of hadrons. The electron is an ideal probe of the proton structure because it provides the unmatched precision of the electromagnetic interaction, as the virtual photon or vector bosons probe the proton structure in a clean environment, the kinematics of which is uniquely determined by the electron beam and the scattered lepton, or the hadronic final state accounting appropriately for radiation.

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. [...]

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..

Chapter 7: R&D; programmes oriented towards specific future facilities : Section 7.1: The FCC-ee R&D; programme
/ Benedikt, M (CERN) ; Blondel, A (KEK, Tsukuba) ; Brunner, O (CERN) ; Janot, P (CERN) ; Jensen, E (CERN) ; Koratzinos, M (MIT) ; Losito, R (CERN) ; Oide, K (KEK, Tsukuba) ; Raubenheimer, T (SLAC ; Novosibirsk, IYF) ; Zimmermann, F (CERN)
In summer 2021, the Future Circular Collider Feasibility Study was launched.
The FCC-ee builds on 60 years of operating colliding beam storage rings. The design is robust and will provide high luminosity over the desired centre-of-mass energy range from 90 to 365 GeV. [...]

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.
