Kevin Nelson developed and integrated a straw tube tracker detector within the ALLEGRO simulation in the key4hep/k4geo repository. He implemented the detector’s geometry in C++ and used CMake and XML configuration to ensure seamless integration with the existing simulation framework. By updating the configuration and adapting tests, Kevin enabled the simulation to more accurately represent detector behavior, supporting downstream physics analyses. His modular approach facilitates future detector additions and accelerates validation cycles. The work demonstrated depth in detector simulation and Geant4, delivering a complete feature that enhances modeling fidelity and supports ongoing development in high-energy physics simulation environments.
