Extending aperture3d for Beam Dynamics Simulations of the High-Level Injector (HLI) at GSI — •Pascal Häckel1, 2, Winfried Barth1, 2, and Uwe Scheeler1 — 1GSI, Darmstadt — 2Hi, Mainz
Beam dynamics simulations play a critical role in understanding and optimizing accelerator systems. In this work, we utilize and extend the capabilities of aperture3d, a versatile beam dynamics simulation framework, to model the High-Level Injector (HLI) at the GSI Helmholtzzentrum für Schwerionenforschung.
The study involves adapting aperture3d to accurately represent the unique components and operational parameters of the HLI, including the ion source, RFQ, and drift tube linac. Enhancements to the software were implemented to accommodate specific requirements, such as detailed beamline geometries, and custom diagnostics for analyzing transverse and longitudinal beam dynamics.
The extended functionality of aperture3d enabled precise simulations of the HLI's performance, highlighting emittance growth mechanisms, beam losses, and potential bottlenecks. These insights not only validate aperture3d as a robust tool for high-intensity accelerator studies but also pave the way for further software improvements tailored to complex accelerator systems.
This work underscores the value of extending modular simulation frameworks like aperture3d for advanced research in beam physics and accelerator optimization.
