Oliver Boine-Frankenheim (TU Darmstadt)12/04/2016, 13:45AcceleratorsOralThis contribution summarizes the impedance and single beam instability studies performed within EuroCirCol WP 2.4 (single beam current limitations). Numerical results for the beam pipe impedance will be presented together with the resulting growth rates for coupled bunch instabilites. The effect of different coatings will be estimated as well as the threshold for transverse mode coupling...Go to contribution page

Vladimir Kornilov (GSI Helmholtzzentrum Darmstadt, Germany)12/04/2016, 14:00AcceleratorsOralDedicated octupole magnets should be employed in the FCC as a cure against transverse collective instabilities, in addition to the transverse feedback system. In the LHC, the Landau octupoles are routinely combined with the chromaticity and the transverse feedback system in order to ensure the bunch stability through the cycle. We estimate the stability provided by an octupole scheme in FCC...Go to contribution page

David Boutin (CEA)12/04/2016, 14:30AcceleratorsOralThe FCC-hh (Future Hadron-Hadron Circular Collider) is one of the three options considered for the next generation accelerator in high-energy physics as recommended by the European Strategy Group, and the natural evolution of existing LHC. Preliminary studies have started to estimate the design parameters of this option. One of these studies is the calculation of the residual orbit in the...Go to contribution page
