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. [...]

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. [...]

Dynamic aperture at injection energy for the HE-LHC
/ Hofer, Michael (CERN ; TU Vienna) ; Giovannozzi, Massimo (CERN) ; Keintzel, Jacqueline (CERN) ; Tomás, Rogelio (CERN) ; Zimmermann, Frank (CERN) ; van Riesen-Haupt, Léon (JAI, UK ; Oxford U.)
As part of the Future Circular Collider study, the High Energy LHC (HE-LHC) is a proposed hadron collider situated in the already existing LHC tunnel. It aims at achieving a center of mass energy of 27 TeV, almost doubling the design c.o.m. [...]

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. [...]

A design study for a future collider to be built in the LHC tunnel, the High-Energy Large Hadron Collider (HE-LHC), has been launched as part of the Future Circular Collider (FCC) study at CERN. It would provide proton collisions at a centre-of-mass energy of 27 TeV as well as collisions of heavy ions at the equivalent magnetic rigidity. [...]

Optics Measurement by Excitation of Betatron Oscillations in the CERN PSB
/ Maclean, Ewen H (CERN) ; Antoniou, Fanouria (CERN) ; Asvesta, Foteini (CERN) ; Bartosik, Hannes (CERN) ; Bracco, Chiara (CERN) ; Dilly, Joschua W (CERN) ; Fol, Elena (CERN) ; Garcia Morales, Hector (CERN) ; Hofer, Michael (CERN) ; Keintzel, Jacqueline (CERN) et al.
Optics measurement from analysis of turn-by-turn BPM data of betatron oscillations excited with a kicker magnet has been employed very successfully in many machines but faces particular challenges in the CERN PSB where BPM to BPM phase advances are sub-optimal for optics reconstruction. Experience using turn-by-turn oscillation data for linear optics measurements during PSB commissioning in2021 is presented, with implications for the prospect of such techniques in the PSB more generally..
