Accumulation of Positrons from a LINAC Based Source / GBAR Collaboration
The GBAR experiment aims to measure the gravitational acceleration of antihydrogen H. It will use H + ions formed by the interaction of antiprotons with a dense positronium cloud, which will require about $10^{10}$ positrons to produce one H + [...]

Bunch characteristics evolution for lepton and hadron rings under the influence of the Intra-beam scattering effect / Papadopoulou, Parthena Stefania (University of Crete (GR))
The physical parameter quantifying particle events’ production and thereby the performance of a collider is the luminosity. High luminosities are reached by increasing the beam brightness, i.e. [...]

Strategy for Landau damping of head-tail instabilities at top energy in the HL-LHC / Buffat, Xavier (CERN) ; Antipov, Sergey ; Arduini, Gianluigi (CERN) ; De Maria, Riccardo (CERN) ; Karastathis, Nikos ; Kostoglou, Sofia (CERN) ; Koval, Adam (University of Dundee (GB)) ; Maclean, Ewen Hamish (CERN) ; Mounet, Nicolas (CERN) ; Papaphilippou, Yannis (CERN) et al.
The main aspects linked to Landau damping of head-tail instabilities at top energy in the HL-LHC are discussed, in particular the interplay between the arc octupoles and long-range, offset or head-on beam-beam interactions as well as lattice imperfections. [...]

Study of the Effect of Detuning Impedance on Beam Stability / Chitnis, Ninad (ETH Zurich (CH)) ; Zannini, Carlo (CERN) ; Mounet, Nicolas (CERN) ; Rumolo, Giovanni (CERN)
The impact of the detuning impedance on the stability of a particle beam is a relatively less studied phenomenon compared to the usual case of considering only the driving impedance [...]

Stochastic cooling pickup/kicker developments for the High-precision Spectrometer Ring in the HIAF Project at IMP / Caspers, Fritz (European Scientific Institute (FR))
Stochastic cooling of the Spectrometer Ring (SRing) at the High Intensity heavy-ion Accelerator Facility (HIAF) project in China, which is used mainly for experiments with radioactive fragment beams, is applied to speed up the cooling process of a stored ion beam. In this study, both a Faltin traveling wave structure and a novel slot-ring standing wave structure based on a ceramic vacuum chamber are discussed and evaluated for the pickup/kicker of the SRing stochastic cooling system.

ESS$\nu$SB Linac Design and Beam Dynamics / Folsom, Benjamin (ESS, Lund) ; Gålnander, Björn (ESS, Lund) ; Eshraqi, Mamad (ESS, Lund) ; Farricker, Aaron (CERN)
The ESS neutrino superbeam project is being studied as an upgrade to the European Spallation Source. This would entail the addition of an $\mathrm{H^-}$ source to the existing beamline to send $\mathrm{H^-}$ pulses in between proton pulses, effectively doubling the beam power from five to ten megawatts.
