Lynn Tung developed and enhanced data acquisition and processing features for the SBNSoftware/sbndaq-artdaq repository over four months, focusing on timing accuracy, data quality, and configuration reliability. Working primarily in C++ on embedded and real-time systems, Lynn refactored timing logic to support multiple reference types, improved waveform handling for robust metric extraction, and optimized configuration defaults to reduce operational risk. She addressed bugs affecting timestamp precision and metric consistency, implemented targeted data filtering, and ensured production-ready code through systematic debugging and code cleanup. Lynn’s work demonstrated depth in firmware integration, error handling, and maintainable software trigger development for DAQ pipelines.

February 2025: Delivered two targeted bug fixes in SBNDaq-artdaq that strengthen data quality and measurement reliability. Refactored peakPE calculation to align with peaktime so both derive from the same waveform point, and refined gate HLT timestamp logic to apply correct conditions for beam vs offbeam streams, improving gated event timestamp accuracy. These changes enhance metric consistency, timestamp precision, and overall pipeline reliability.
