CEPC Technical Design Report: Accelerator
/ CEPC Study Group Collaboration
The Circular Electron Positron Collider (CEPC) is a large scientific project initiated and hosted by China, fostered through extensive collaboration with international partners. The complex comprises four accelerators: a 30 GeV Linac, a 1.1 GeV Damping Ring, a Booster capable of achieving energies up to 180 GeV, and a Collider operating at varying energy modes (Z, W, H, and ttbar). [...]

Impact of Bunch Current on Optics Measurements in SuperKEKB
/ Keintzel, Jacqueline (CERN ; TU Vienna) ; Ishibashi, Takuya (KEK, Tsukuba) ; Koiso, Haruyo (KEK, Tsukuba) ; Mitsuka, Gaku (KEK, Tsukuba) ; Morita, Akio (KEK, Tsukuba) ; Ohmi, Kazuhito (KEK, Tsukuba) ; Ohnishi, Yukiyoshi (KEK, Tsukuba) ; Sugimoto, Hiroshi (KEK, Tsukuba) ; Terui, Shinji (KEK, Tsukuba) ; Tobiyama, Makoto (KEK, Tsukuba) et al.
SuperKEKB has recently achieved the world record instantaneous luminosity of 2.8 × 10³⁴ \si{cm⁻²s⁻¹} and aims at reaching a target luminosity of about 6 × 10³⁵ \si{cm⁻²s⁻¹}. To accomplish this goal it is planned to increase beam currents up to §I{3.6}{A} and §I{2.6}{A} for the positron and the electron ring, respectively. [...]

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. [...]

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. [...]
