During February 2025, D. Henis focused on stabilizing the Lindhard-Robinson ionization yield model within the kelseymh/G4CMP repository. Henis addressed a ChangeHistory conflict by introducing a dedicated entry for the model fix, ensuring accurate project documentation and traceability. The work involved C++ code maintenance and targeted testing, specifically refining the testNRyield.cc file to correct atomic mass calculations. This adjustment improved the accuracy and reproducibility of unit tests, directly enhancing the reliability of downstream simulations. Although the period did not include new feature development, Henis demonstrated depth in debugging and maintaining scientific code, emphasizing careful validation and sustainable code practices.
