Octupole magnets are a central mitigation method against the transverse collective instabilities expected for the high-intensity operation of the SIS18 and SIS100 synchrotrons in the FAIR project. For these beam parameters, the self-field space-charge effect dominates the betatron footprint, and strongly modifies the instability drive and the Landau damping properties. The space-charge tune shifts are related to all three incoherent amplitudes, and is an intrinsic interaction. We consider all these effects and study Landau damping of head-tail modes due to the combination of octupoles and space-charge. Using the data from experimental instability observations, and particle tracking simulations, we provide estimations for the expected high-intensity operation of the SIS synchrotrons. 899 - ohne Topic (POF4-899) G:(DE-HGF)POF4-899 POF4-899 POF IV 0 Dataset connected to DataCite Accelerator Physics Other mc5-beam-dynamics-and-em-fields - MC5: Beam Dynamics and EM Fields Other mc5-d06-coherent-and-incoherent-instabilities-measurements-and-countermeasures - MC5.D06: Coherent and Incoherent Instabilities Measurements and Countermeasures 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 Kornilov, Vladimir P:(DE-Ds200)OR0625 1 Corresponding author 10.18429/JACOW-IPAC2023-WEPA015 OpenAccess http://repository.gsi.de/record/358338/files/WEPA015.pdf OpenAccess pdfa http://repository.gsi.de/record/358338/files/WEPA015.pdf?subformat=pdfa oai:repository.gsi.de:358338 openaire open_access VDB driver dnbdelivery GSI Helmholtzzentrum für Schwerionenforschung GmbH I:(DE-Ds200)20121206GSI GSI 1 P:(DE-Ds200)OR0625 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 2023 OpenAccess StatID:(DE-HGF)0510 StatID Creative Commons Attribution CC BY 4.0 LIC:(DE-HGF)CCBY4 HGFVOC no I:(DE-Ds200)APH-20060809OR090 APH Accelerator Physics 0 contrib VDB UNRESTRICTED I:(DE-Ds200)APH-20060809OR090 FullTexts
