Andrew Holbrook contributed to the bmad-sim/BeamTracking.jl repository by developing and refining particle tracking features for accelerator physics simulations. Over three months, he implemented exact bend physics and enhanced dipole and sector-bend support, focusing on numerical stability and robust handling of edge cases such as lost-state particles. His work involved extensive code refactoring, improved test coverage, and updates to documentation, all using Julia and scientific computing techniques. By expanding and validating the test suite, updating APIs, and increasing matrix precision, Andrew delivered more reliable simulation outputs and maintainable code, supporting accurate accelerator design and ongoing development within the BeamTracking.jl project.
