Description

At the Electron Ion Collider's Hadron Injector, the Alternating Gradient Synchrotron (AGS), space charge effects at injection remain a key factor that limits the polarized proton beam quality. Minimizing the emittance growth is essential for delivering high luminosity and minimizing polarization loss during acceleration. In this paper, we present Xsuite simulations of beam dynamics during AGS injection of high-intensity polarized proton beams. Benchmarking against available experimental measurements is performed to validate the implemented model and quantify the role of space charge in the beam parameters such as the space charge tune shifts and transverse emittance growth. The simulation is then used to evaluate the potential benefits of increasing the AGS injection energy and provide guidance for future high-intensity operations.
