Multiphysics Simulations of the Wide Opened Waveguide Crab-cavity
/ Papke, Kai (CERN) ; Amorim Carvalho, Alexandre (CERN) ; Grudiev, Alexej (CERN) ; Zanoni, Carlo (CERN)
In the frame of a FCC study a first prototype of a compact superconducting crab-cavity, using Nb-on-Cu-coating technique is being manufactured and investigated. The design, which is based on the ridged waveguide resonator, is subjected to multipacting and pressure sensitivity simulations. [...]

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. [...]

Superconducting RF cavity developments are currently on-going for new accelerator projects at CERN such as HIE ISOLDE and HL-LHC. Mechanical RF tuning systems are required to compensate cavity frequency shifts of the cavities due to temperature, mechanical, pressure and RF effects on the cavity geometry. [...]
