During November 2024, M U Pitt developed a fully configurable B0 ECAL geometry for the eic/epic repository, focusing on enhancing detector simulation realism and flexibility. Using C++ and leveraging expertise in geometry definition, Pitt introduced new configuration hooks that allow rapid scenario testing and improved detector positioning. The work included adding a B0 exit window to the ECAL, which supports more realistic simulation outcomes. By updating geometry definitions, Pitt improved the resolution and acceptance of the ECAL, thereby strengthening simulation fidelity. This engineering effort established a robust foundation for future modeling, validation workflows, and analytics across related detector studies.
