Optimizing Beam-Plasma Interactions Through Jitter Analysis Using Start-to-End Simulations

Abstract: Traditional accelerators, while effective, suffer from extensive spatial and financial demands, necessitating the exploration of compact alternatives like PWFA, which significantly reduces the necessary accelerator length by utilizing the wake generated by a high-speed pulse traveling through plasma. Our research focuses on mitigating instabilities, particularly timing jitter, which critically impacts the quality of accelerated beams. Through the deployment of Impact-T, Bmad, and Tao simulation tools at the FACET-II facility, we examined how timing jitter influences key beam parameters, including peak currents and emittance, over various simulation scenarios. The findings reveal that even minute variations in accelerator settings can significantly influence beam characteristics, underscoring the importance of precise control in beam dynamics. The outcomes contribute to enhancing the reliability and precision of PWFA systems, promising improved applications in both scientific research and medical therapies. Future research directions include integrating machine learning techniques to refine control strategies further and reduce experimental redundancies, highlighting the evolving synergy between accelerator physics and computational data science.
