 New NA22 Results on Correlations / de Wolf, E A (Antwerp U.) Recent NA22 results from $\pi^+p$ and $K^+p$ inelastic interactions at $\sqrt{s}$= 22 GeV on invariant-mass and $Q^2$-dependence of two-and three-particle factorial cumulants are discussed in relation to earlier intermittency studies. The absence of Bose- Einstein type correlations among identical particles, and too large resonance production rates, are responsible for the strong disagreements of models with intermittency data..

 The ratio $F^n_2$ / $F^p_2$ and the A dependence of nuclear ratios measured by NMC / Seitz, R (Mainz U., Inst. Kernphys.) ; Witzmann, A (Freiburg U.) /NMC Results are presented on the structure function ratio $F^n_2$ / $F^p_2$ and the A dependence of nuclear ratios $F^A_2$ / $F^C_2$ in deep inelastic muon scattering. Results were obtained for the hydrogen and deuterium targets with several incident energies, and for the nuclear targets at 200 GeV incident muon energy. [...] Gif-Sur-Yvette : Ed.

 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).
