Space charge effects are the main limitation for the brightness performance of the Proton Synchrotron Booster (PSB) at CERN. Following the upgrades of the LHC Injectors Upgrade (LIU) project, the PSB delivered unprecedented brightness even exceeding the projected target parameters. A possibility for further increasing the brightness is to operate above the half-integer resonance 2Q_{y}=9 in order to avoid emittance blow-up from resonances at Q_{x,y}=4 due to the strong space charge detuning. The half-integer resonance can be compensated to a great extent using the available quadrupole correctors in the PSB, and also deliberately excited in a controlled way. The control of the half-integer resonance and the flexibility of the PSB to create a variety of different beam and machine conditions allowed the experimental characterization of space charge effects near this resonance. This contribution reports the experimental observations of the particle trapping during the dynamic crossing of the half-integer, as well as systematic studies of the beam degradation from space charge induced resonance crossing. 899 - ohne Topic (POF4-899) G:(DE-HGF)POF4-899 POF4-899 POF IV 0 Dataset connected to DataCite Accelerator Physics Other Beam Dynamics in Rings Other theory no experiment theory work (theory) EXP:(DE-Ds200)theory-20200803 EXP:(DE-Ds200)no_experiment-20200803 EXP:(DE-Ds200)no_experiment-20200803 0 Antoniou, Fanouria P:(DE-HGF)0 1 Asvesta, Foteini P:(DE-HGF)0 2 Bartosik, Hannes P:(DE-HGF)0 3 Franchetti, Giuliano P:(DE-Ds200)OR0314 4 10.18429/JACOW-HB2023-THBP19 OpenAccess http://repository.gsi.de/record/358327/files/thbp19-1.pdf OpenAccess pdfa http://repository.gsi.de/record/358327/files/thbp19-1.pdf?subformat=pdfa oai:repository.gsi.de:358327 openaire open_access VDB driver dnbdelivery GSI Helmholtzzentrum für Schwerionenforschung GmbH I:(DE-Ds200)20121206GSI GSI 4 P:(DE-Ds200)OR0314 DE-HGF Programmungebundene Forschung ohne Programm G:(DE-HGF)POF4-890 G:(DE-HGF)POF4-899 G:(DE-HGF)POF4 G:(DE-HGF)POF4-800 G:(DE-HGF)POF ohne Topic 0 2025 OpenAccess StatID:(DE-HGF)0510 StatID Creative Commons Attribution CC BY 4.0 LIC:(DE-HGF)CCBY4 HGFVOC no I:(DE-Ds200)STR-20121002OR239 STR Speicherringe 0 contrib VDB UNRESTRICTED I:(DE-Ds200)STR-20121002OR239 FullTexts
