Aperture measurements with AC dipole / Fuster Martinez, Nuria (CERN) ; Maclean, Ewen Hamish (CERN) ; Dilly, Joschua Werner (Ministere des affaires etrangeres et europeennes (FR)) ; Nevay, Laurence James (University of London (GB)) ; Bruce, Roderik (CERN) ; Tomas Garcia, Rogelio (CERN) ; Redaelli, Stefano (CERN) ; Persson, Tobias Hakan Bjorn (CERN)
During the MDs performed on the 15th of September and 29th of November 2017, we measured the LHC global aperture at injection with a new AC dipole method as well as using the Transverse Damper (ADT) blow-up method used during the 2017 LHC commissioning for benchmarking. [...]

Space charge driven beam loss for cooled beams and mitigation measures in the CERN Low Energy Ion Ring / Bartosik, Hannes (CERN) ; Hancock, Steven (CERN) ; Huschauer, Alexander (CERN) ; Kain, Verena (CERN)
The performance of the CERN Low Energy Ion Ring (LEIR) with electron cooled lead ion beams is presently limited by losses, which occur during RF capture and the first part of acceleration. Extensive experimental studies performed in 2015 indicate that the losses are caused by the interplay of betatron resonances and the direct space charge detuning, which is significantly enhanced during bunching.

On the impact of non-symplecticity of space charge solvers / Titze, Malte (CERN)
To guarantee long-term reliability in the predictions of a numerical integrator, it is a well-known requirement that the underlying map has to be symplectic. It is therefore important to examine in detail the impact on emittance growth and noise generation in case this condition is violated. [...]

Overview of the ESSnuSB accumulator ring / Olvegård, Maja (Uppsala U.) ; Benedetto, Elena (CERN) ; Cieslak-Kowalska, Magdalena (CERN) ; Ekelöf, Tord (Uppsala U.) ; Martini, Michel (CERN) ; Schönauer, Horst (CERN) ; Wildner, Elena (CERN)
The European Spallation Source (ESS) is a research center based on the world’s most powerful proton driver, 2.0 GeV, 5 MW on target, currently under construction in Lund. With an increased pulse frequency, the ESS linac could deliver additional beam pulses to a neutrino target, thus giving an excellent opportunity to produce a high-performance ESS neutrino Super-Beam (ESSnuSB).
