HOM Mitigation for FCC-ee / Novokhatski, Alexander (SLAC)
High electron and positron currents (1.5 A) are planned to be used in the Future Circular electron-positron Collider (FCC-ee) with a goal to archive high luminosity of order of 2.3 1036 cm-2s-2 at the Z-production collision at the beam energy of 45.6 GeV [1, 2]. Coherent effects at the high-current machine impose certain limitations on the magnitude of the impedance of the machine. [...]

Interaction Region for the FCC-ee Design / Boscolo, Manuela (Frascati) ; Sullivan, M K (SLAC)
We present here a current snapshot of the Interaction Region (IR) design for the Future Circular Collider electron-positron accelerator (FCC-ee) [1]. We introduce the IR design based on accelerator requirements and describe the additional details important in the study of backgrounds in the detector as well as to the needs of the detector. [...]

Cable Design and Development for the High-Temperature Superconductor Cable Test Facility Magnet / Pong, Ian (LBNL, Berkeley) ; Hafalia, Aurelio (LBNL, Berkeley) ; Higley, Hugh (LBNL, Berkeley) ; Lee, Elizabeth (LBNL, Berkeley) ; Lin, Andy (LBNL, Berkeley) ; Naus, Michael (LBNL, Berkeley) ; Perez, Carlos (LBNL, Berkeley) ; Prestemon, Soren (LBNL, Berkeley) ; Sabbi, GianLuca (LBNL, Berkeley) ; Hopkins, Simon (CERN) et al.
A large bore “High-Temperature Superconductor Cable Test Facility Magnet” for testing advanced cables and inserts in high transverse field is in its design phase. This magnet will be the core component of a facility for developing conductors and accelerator magnets operating above 15 T, an enabling technology for next-generation fusion devices using magnetic confinement of plasma and for future energy frontier colliders.

Top-up injection schemes for future circular lepton collider / Aiba, M (PSI, Villigen) ; Goddard, B (CERN) ; Oide, K (CERN ; KEK, Tsukuba) ; Papaphilippou, Y (CERN) ; Saá Hernández, Á (PSI, Villigen) ; Shwartz, D (Novosibirsk, IYF) ; White, S (ESRF, Grenoble) ; Zimmermann, F (CERN)
Top-up injection is an essential ingredient for the future circular lepton collider (FCC-ee) to maximize the integrated luminosity and it determines the design performance. In ttbar operation mode, with a beam energy of 175 GeV, the design lifetime of ∼ 1 h is the shortest of the four anticipated operational modes, and the beam lifetime may be even shorter in actual operation.

Future Circular Collider: Integrated Programme and Feasibility Study / Benedikt, Michael (CERN) ; Zimmermann, Frank (CERN)
The Future Circular Collider (FCC) Integrated Project foresees, in a first stage, a high-luminosity high-energy electron-positron collider, serving as Higgs, top and electroweak factory, and, in a second stage, an energy frontier hadron collider, with a centre-of-mass energy of at least 100 TeV. This programme well matches the highest priority future requests issued by the 2020 Update of the European Strategy for Particle Physics. [...]

Considerations on combined-function optics for high-energy storage rings and colliders / Giovannozzi, M (CERN)
In a recent paper, the proposal of using combined-function optics for the arcs of the Future Circular hadron Collider (FCC–hh) was presented and discussed in detail. In this paper, further considerations are presented on the same topic, reflecting the progress made since the previous publication. [...]

Mechanical characterization of yarns made from carbon nanotubes for the instrumentation of particle beams at CERN / Mariet, A (CERN) ; Perez Fontenla, A T (CERN) ; Gabrion, X (FEMTO-ST) ; Salomon, C (Savoie U. (main)) ; Veness, R (CERN) ; Devel, M
Existing copper-coated carbon fibers used in wire scanners to measure the transverse beam profile in the accelerators at CERN are approaching material limits. A new instrument design has showed that the main limitation now comes from the centerpiece of the instrument: the wire. [...]
