Alex He

Worked on the bmad-sim/BeamTracking.jl repository to enhance particle accelerator simulation capabilities by implementing and refining exact bend physics for particle tracking. Focused on improving the reliability and accuracy of the ExactTracking core, the work included refactoring code for numerical stability, expanding support for dipole and sector bends, and strengthening test coverage using test-driven development. Leveraged Julia and scientific computing techniques to update documentation, validate results against external tools, and streamline API usage. Addressed robustness in lost-state handling and improved maintainability through code formatting and refactoring, resulting in more dependable simulation outputs and a clearer foundation for future development.
