In response to the 2013 Update of European Strategy for Particle Physics, Future Circular Collider (FCC) study was launched, as an international collaboration hosted by CERN. This covers a highest-luminosity high-energy lepton collider (FCC-ee) and energy-frontier hadron (FCC-hh), which could, successively, be installed in same 100 km tunnel. The scientific capabilities integrated FCC programme would serve worldwide community throughout 21st century. also investigates LHC energy upgrade,...
We review the physics opportunities of Future Circular Collider, covering its e+e-, pp, ep and heavy ion programmes. describe measurement capabilities each FCC component, addressing study electroweak, Higgs strong interactions, top quark flavour, as well phenomena beyond Standard Model. highlight synergy complementarity different colliders, which will contribute to a uniquely coherent ambitious research programme, providing an unmatchable combination precision sensitivity new physics.
In response to the 2013 Update of European Strategy for Particle Physics (EPPSU), Future Circular Collider (FCC) study was launched as a world-wide international collaboration hosted by CERN. The FCC covered an energy-frontier hadron collider (FCC-hh), highest-luminosity high-energy lepton (FCC-ee), corresponding 100 km tunnel infrastructure, well physics opportunities these two colliders, and LHC, based on FCC-hh technology.

The resistive wall impedance is one of the expected main drivers transverse beam instabilities in proposed Future Circular Collider hadron-hadron option (FCC-hh). We obtain for FCC-hh screen from a two-dimensional finite element solver. impedances and resulting growth rates are compared to LHC, using similar models resistivity copper layer. Similar LHC addition active feedback, dedicated octupole magnets together with chromaticity should be employed Landau damping, as cure against...
The use of high temperature superconducting (HTS) materials can enhance the performance undulators (SCU), which later be implemented in free electron laser facilities, synchrotron storage rings and light sources. In particular, short period < 10 mm with narrow magnetic gap 4 are relevant. One promising approaches considers a cm meander-structured HTS tapes stacked one above other. Then, tape is wound on SCU. idea this jointless undulator has been proposed by, being further developed at KIT....
To produce small-scale high-field undulators for table-top free electron lasers (FELs), compact designs have been proposed using high temperature superconducting (HTS) tapes, which show both large critical current densities and magnetic fields with a total tape thickness of about 50 μm width up to 12 mm. Instead winding coils, meander structure can be laser-scribed directly into the superconductor layer, guiding path on quasi-sinusoidal trajectory. Stacking pairs such scribed tapes allows...
To produce radiation in the THz frequency range at X-ray Free Electron Lasers, undulators with large period length, high fields, and gaps are required. These demands can be fulfilled by superconducting undulators. In this contribution, actual requirements on main parameters of such a undulator will discussed progress design discussed. addition, beam impedance heat load results obtained analytically as well large-scale wakefield simulations presented.
