Revised Collimation Configuration for the Updated FCC-hh Layout
/ Abramov, Andrey (CERN) ; Bruce, Roderik (CERN) ; Giovannozzi, Massimo (CERN) ; Pérez Segurana, Gustavo (CERN) ; Redaelli, Stefano (CERN) ; Risselada, Thys (CERN)
The collimation system for the hadron Future Circular Collider (FCC-hh) must handle proton beams with an unprecedented nominal beam energy and stored beam energy in excess of 8 GJ, and protect the superconducting magnets and other sensitive equipment while ensuring a high operational efficiency. The recent development of the 16-dipole lattice baseline for the FCC-hh, and the associated layout changes, has necessitated an adaptation of the collimation system. [...]

Collimation system studies for the FCC-hh

The Future Circular Collider (FCC-hh) is being designed as a 100 km ring that should collide 50 TeV proton beams. At 8.3 GJ, its stored beam energy will be a factor 28 higher than what has been achieved in the Large Hadron Collider, which has the highest stored beam energy among the colliders built so far. [...]

Updated High-Energy LHC design

Inst.) ; Arsenyev, Sergey (CERN) ; Barranco, Javier (Ecole Polytechnique, Lausanne) ; Benedikt, Michael (CERN) ; Bruce, Roderik (CERN) et al.
We present updated design parameters for a future High-Energy LHC. A more realistic turnaround time has led to a revision of the target peak luminosity, as well as a choice of a larger IP beta function, and longer physics fills. [...]

Design of a Collimation Section for the FCC-ee
/ Hofer, Michael (CERN) ; Abramov, Andrey (CERN) ; Bruce, Roderik (CERN) ; Moudgalya, Maitreyee (Ecole Polytechnique, Lausanne) ; Oide, Katsunobu (CERN) ; Pieloni, Tatiana (Ecole Polytechnique, Lausanne) ; Zimmermann, Frank (CERN)
The design parameters of the FCC-ee foresee operation with a total stored beam energy of about 20 MJ, exceeding those of previous lepton colliders by almost two orders of magnitude. Given the inherent damage potential, a halo collimation system is studied to protect the machine hardware, in particular superconducting equipment such as the final focus quadrupoles, from sudden beam loss.

HE-LHC optics design options

The High Energy Large Hadron Collider (HE-LHC), a possible successor of the High Luminosity Large Hadron Collider (HL-LHC) aims at reaching a centre-of-mass energy of about 27 TeV using basically the same 16 T dipoles as for the hadron-hadron Future Circular Collider FCC-hh. Designing the HE-LHC results in a trade off between energy reach, beam stay clear as well as geometry offset with respect to the LHC. [...]

Collimation system for the updated FCC-hh design baseline
/ Abramov, A (CERN) ; Bruce, R (CERN) ; Giovannozzi, M (CERN) ; Perez-Segurana, G (CERN) ; Redaelli, S (CERN) ; Risselada, T (CERN)
For the Future Circular Collider (FCC) Conceptual Design Report (CDR), the FCC-hh collimation system was studied and optimized for proton and heavy-ion operation with up to 8.3 GJ stored beam energy. There are currently studies ongoing for an updated design baseline, including a new ring layout, compatible with the FCC-ee, and optics, where the collimation insertions have undergone major changes.

Optimized Arc Optics for the HE-LHC

The High Energy LHC (HE-LHC) proton-proton collider is a proposed replacement of the LHC in the existing 27-km tunnel, with the goal of reaching the centre-of-mass beam energy of 27 TeV. The required higher dipole field can be realized by using 16-T dipoles being developed for the FCC-hh design. [...]
