Overall Injection Strategy for FCC-ee
/ Ogur, Salim (CERN) ; Aiba, Masamitsu (PSI, Villigen) ; Antoniou, Fanouria (CERN) ; Barnyakov, Alexey (Novosibirsk, IYF) ; Chaikovska, Iryna (Orsay, LAL) ; Charles, Tessa (CERN) ; Chehab, Robert (Orsay, LAL) ; Etisken, Ozgur (Ankara U.) ; Furukawa, Kazuro (KEK, Tsukuba) ; Härer, Bastian (CERN) et al.
The Future Circular electron-positron Collider (FCC-ee) requires fast cycling injectors with very low extraction emittances to provide and maintain extreme luminosities at center of mass energy varying between 91.2-385 GeV in the collider. For this reason, the whole injector complex table is prepared by putting into consideration the minimum fill time from scratch, bootstrapping, transmission efficiency as well as store time of the beams in synchrotrons to approach equilibrium emittances.

We report the design of the pre-injector chain for the Future Circular e$^+$e$^−$ Collider (FCC-ee) system. The electron beam from a low-emittance RF gun is accelerated by an S-band linac up to 6 GeV. [...]

First results of the compensation of the beam-beam effect with DC wires in the LHC
/ Sterbini, Guido (CERN) ; Amorim, David (CERN ; Grenoble, INP) ; Bartosik, Hannes (CERN) ; Bertarelli, Alessandro (CERN) ; Bruce, Roderik (CERN) ; Buffat, Xavier (CERN) ; Carra, Federico (CERN) ; Carver, Lee (CERN) ; Cattenoz, Gregory (CERN) ; Effinger, Ewald (CERN) et al.
The compensation of the long-range beam-beam interactions using DC wires is presently under study as an option for enhancing the machine performance in the framework of the High-Luminosity LHC Project (HL-LHC). The original idea dates back more than 15 years ago. [...]

Layout and Performance of the FCC-ee Pre-Injector Chain
/ Ogur, Salim (CERN ; Bogazici U.) ; Charles, Tessa (CERN ; Melbourne U.) ; Oide, Katsunobu (CERN ; KEK, Tsukuba) ; Barnyakov, Alexey (Novosibirsk, IYF) ; Chaikovska, Iryna (Orsay, LAL) ; Rinolfi, Louis (CERN) ; Chehab, Robert (Orsay, LAL) ; Furukawa, Kazuro (KEK, Tsukuba) ; Iida, Naoko (KEK, Tsukuba) ; Kamitani, Takuya (KEK, Tsukuba) et al.
The Future Circular e + e − Collider pre-injector chain consists of a 6 GeV S-Band linac, a damping ring at 1.54 GeV and pre-booster ring to reach 20 GeV for injection to the main booster. The electron and positron beams use the same accelerator chain alternatively. [...]

Towards a Preliminary FCC-ee Injector Design
/ Ogur, Salim (CERN ; Bogazici U.) ; Barnyakov, Alexey (Novosibirsk, IYF) ; Furukawa, Kazuro (KEK, Tsukuba) ; Iida, Naoko (KEK, Tsukuba) ; Levichev, Alexey (Novosibirsk, IYF) ; Miyahara, Fusashi (KEK, Tsukuba) ; Nikiforov, Danila (Novosibirsk, IYF) ; Oide, Katsunobu (KEK, Tsukuba) ; Papaphilippou, Yannis (CERN) ; Zimmermann, Frank (CERN)
The Future Circular Collider-ee aims to get high luminosity which mainly relies upon high charge and low geometric emittance in the collider. The FCC-ee is a future project of CERN to operate as Z, W, H and tt factories with varying energies between 45.6 to 175 GeV. [...]

Progress with Long-Range Beam-Beam Compensation Studies for High Luminosity LHC
/ Rossi, Adriana (CERN) ; Aberle, Oliver (CERN) ; Albertone, Joel (CERN) ; Barnyakov, Alexey (Novosibirsk, IYF) ; Bertarelli, Alessandro (CERN) ; Boccard, Christian (CERN) ; Carra, Federico (CERN) ; Cattenoz, Gregory (CERN) ; Delaup, Yorick (CERN) ; Fartoukh, Stephane (CERN) et al.
Long-range beam-beam (LRBB) interactions can be a source of emittance growth and beam losses in the LHC during physics and will become even more relevant with the smaller '* and higher bunch intensities foreseen for the High Luminosity LHC upgrade (HL-LHC), in particular if operated without crab cavities. Both beam losses and emittance growth could be mitigated by compensat-ing the non-linear LRBB kick with a correctly placed current carrying wire. [...]
