During October 2025, Steinber worked on the eic/epic repository, focusing on geometry configuration and physics simulation using C++. He delivered a targeted fix to the Calorimeter Endcap geometry, increasing the ForwardServiceGap_length by 2.8 cm to ensure the LFHCAL endcap aligned precisely with the official project envelope. This adjustment brought the simulation’s maximum z-position into compliance with the 9-22-25 envelope specification, directly addressing a documented misalignment. Steinber’s work improved the reliability of downstream analyses and planning by making the simulation geometry traceable, reproducible, and fully compliant with project parameters, demonstrating careful attention to project constraints and technical accuracy.
