PROFILE
Vu Chi Lan Nguyen
Vinh Nguyen enhanced timestamping precision in the SBNSoftware repositories, focusing on sbndcode and sbnobj. He implemented picosecond-level support in the SPECTDCDecoder module, updating data decoding logic to propagate high-resolution timestamps from TDCTimestampFragment. In sbnobj, he extended the DAQTimestamp structure with a new field for picoseconds and introduced dual constructors to maintain backward compatibility. Working exclusively in C++, he applied careful API design and data structure refactoring to ensure seamless integration with existing pipelines. These changes improved event alignment and data fidelity, addressing the need for more accurate event ordering in physics analyses without disrupting established workflows.

Feb 1, 2025February 2025 performance summary: Delivered high-precision timestamping enhancements across SBNSoftware sbndcode and sbnobj, enabling picosecond-level timestamps and preserving backward compatibility. Implementations include: 1) SPECTDCDecoder: picosecond timestamping added to FragToDAQTimestamp with TDCTimestampFragment; commit b311e31ae479830ccdb4b55034e9c3c60481b515. 2) SBNObj: DAQTimestamp now includes fTimestampPs for picoseconds, with two constructors for backward compatibility; commit 906edf7b82a77202108e307a080dea812a749ed0. These changes jointly improve data fidelity, event alignment, and integration with existing pipelines, yielding clearer analytics and stronger traceability. Technologies demonstrated: C++ timestamping/DAQ structures, API design for backward compatibility, and careful refactoring to avoid breaking changes.
