The reason is related to power supply ripples that act on the quadrupole magnets, leading to unintended tune fluctuations during extraction. Related simulations regarding the dependency of spill quality on the power supply ripples are executed with varying excitation levels of the sinusoidal ripples and bandwidth-limited white noise. In addition, transit time spread is simulated, a few simulation approaches are proposed, and related data analysis procedures and preliminary results are described.JACoW Publishing 2435-2438 pages (2023). doi:10.18429/JACOW-IPAC2023-TUPM097info:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/publishedVersion14th International Particle Accelerator Conference, Venice, Italy, 2023-05-07 - 2023-05-12JACoW Publishing2023info:eu-repo/semantics/openAccessDEhttps://repository.gsi.de/record/357724https://repository.gsi.de/search?p=id:%22GSI-2025-00416%22Researchersinfo:eu-repo/semantics/altIdentifier/doi/10.15120/GSI-2025-00416info:eu-repo/semantics/altIdentifier/doi/10.18429/JACOW-IPAC2023-TUPM097
