Impact of process parameters and design options on heat leaks of straight cryogenic distribution lines / Duda, Pawel (Wroclaw University of Technology (PL)) ; Chorowski, Maciej Pawel ; Polinski, J (Wroclaw University of Technology (PL))
The Future Circular Collider (FCC) accelerator will require a helium distribution system that will exceed the presently exploited transfer lines by almost 1 order of magnitude. The helium transfer line will contain five process pipes protected against heat leaks by a common thermal shield. [...]

Dump system concepts for the Future Circular Collider / Bartmann, Wolfgang (CERN) ; Atanasov, Miroslav Georgiev (CERN) ; Barnes, Mike (CERN) ; Borburgh, Jan (CERN) ; Burkart, Florian (CERN) ; Goddard, Brennan (CERN) ; Kramer, Thomas (CERN) ; Lechner, Anton (CERN) ; Sanz Ull, Alejandro (Eindhoven Technical University (NL)) ; Schmidt, Rudiger et al.
The Future Circular Collider (FCC-hh) beam dump system must provide a safe and reliable extraction and dilution of the stored beam onto a dump absorber. Energy deposition studies show that damage limits of presently used absorber materials will already be reached for single bunches at 50 TeV. [...]

Most critical collimator-mask-magnet sequence in the SPS-to-LHC transfer lines: energy deposition study. / Marzo, Matteo (CERN) ; Cerutti, Francesco (CERN) ; Lechner, Anton (CERN) ; Vlachoudis, Vasilis (CERN)
This technical note refers to a study on the relation between the impact conditions of the SPS 450GeV proton beam and the energy deposited downstream the Target Collimator Dump In- jection Long (TCDIL) collimators [1], in the SPS-to-LHC transfer lines TI2 and TI8. [...]

A code for optimising triplet layout / Van Riesen-Haupt, Leon ; Seryi, Andrei (University of Oxford (GB)) ; Abelleira, Jose ; Cruz Alaniz, Emilia
One of the main challenges when designing final focus systems of particle accelerators is maximising the beam stay clear in the strong quadrupole magnets of the inner triplet. Moreover it is desirable to keep the quadrupoles in the inner triplet as short as possible for space and costs reasons but also to reduce chromaticity and simplify corrections schemes. [...]

Overview of design development of FCC-hh Experimental Interaction Regions / Seryi, Andrei (University of Oxford (GB)) ; Abelleira, Jose ; Cruz Alaniz, Emilia ; Van Riesen-Haupt, Leon ; Benedikt, Michael (CERN) ; Besana, Maria Ilaria (CERN) ; Buffat, Xavier (CERN) ; Burkhardt, Helmut (CERN) ; Cerutti, Francesco (CERN) ; Langner, Andy Sven (CERN) et al.
The experimental interaction region (EIR) is one of the key areas that define the performance of the Future Circular Collider. In this overview we will describe the status and the evolution of the design of EIR of FCC-hh, focusing on design of the optics, energy deposition in EIR elements, beam-beam effects and machine detector interface issues..

Equalizer design techniques for dispersive cables with application to the SPS wideband kicker / Platt, Jason (SLAC) ; Hofle, Wolfgang (CERN) ; Pollock, Kristin (SLAC) ; Fox, John (SLAC)
A wide-band vertical instability feedback control system in development at CERN requires 1–1.5 GHz of bandwidth for the entire processing chain, from the beam pickups through the feedback signal digital processing to the back-end power amplifiers and kicker structures. Dispersive effects in cables, amplifiers, pickup and kicker elements can result in distortions in the time domain signal as it proceeds through the processing system, and deviations from linear phase response reduce the allowable bandwidth for the closed-loop feedback system.
