Description

Intra-Beam Stripping (IBS) Intra-Beam Stripping (IBS) is a critical beam loss mechanism in high-intensity H− Linear Accelerators (linacs) and presents a significant limitation to increasing beam power. This work presents a computational framework to evaluate and mitigate IBS-induced beam losses along the Spallation Neutron Source (SNS) linac. The calculation is based on an analytic theory and is benchmarked against simplified analytically solvable cases. We first apply our algorithm to analytically defined Gaussian bunches. We then extend our algorithm to handle arbitrary bunch distributions using Neural Spline Flow (NSF) models trained on PyORBIT tracking data. Within the scope of this project, we plan to optimize our algorithm, validate it experimentally, and apply it to demonstrate effective mitigation strategies.
