The Gamma Factory path to high-luminosity LHC with isoscalar beams / Krasny, M W (Paris U., VI-VII ; CERN) ; Petrenko, A (Novosibirsk, IYF ; CERN) ; Płaczek, W (Jagiellonian U. (main))
There are two main ways to increase LHC luminosity without upgrading CERN injectors: (1) modification of beam-collision optics and (2) reduction of beam transverse emittance. The former is followed in the ongoing high-luminosity upgrade of the LHC (HL-LHC), while the latter, applicable only to ion beams, is described in this contribution [...]

Conceptual design of an off-momentum collimation system in the CERN Super Proton Synchrotron for High-Luminosity Large Hadron Collider proton beams / Patecki, Marcin (CERN) ; Mereghetti, Alessio (CERN) ; Mirarchi, Daniele (CERN) ; Redaelli, Stefano (CERN)
The CERN accelerator complex is undergoing an upgrade in order to meet the requirements of the High-Luminosity Large Hadron Collider (HL-LHC). One of the key needs is to increase the intensity of beams injected into the LHC from the current $1.15 \times 10^{11}$ to $2.3 \times 10^{11}$ $p^+ $ /bunch. [...]
