PROFILE
Eiad Hamwi
Ethan worked on the bmad-sim/BeamTracking.jl repository, focusing on enhancing and stabilizing exact particle tracking for high-energy physics simulations. Over three months, he refactored patch tracking into modular kernels, improved rotation and drift handling, and standardized charge conventions to align with APC and Bmad standards. Using Julia and leveraging numerical methods, he optimized kernel performance, reduced allocations, and expanded test coverage to ensure simulation accuracy and maintainability. His work included fixing calculation bugs, streamlining test infrastructure, and enabling configurable patch behavior, resulting in a more robust, reliable, and maintainable codebase for scientific computing and particle accelerator studies.

Jul 1, 2025July 2025 focused on stabilizing and modularizing patch tracking in BeamTracking.jl. Key refactor separated patch tracking into distinct kernels (offset, rotation, exact_drift) and extended SplitIntegration with a new patch_rotation parameter. These changes improve configurability and maintainability, reduce drift modeling complexity, and passed the full test suite, supporting more robust simulations and easier future enhancements.
