PROFILE
Stephen Greenberg
Over four months, contributed to the DUNE/ndlar_flow repository by developing and refining charge reconstruction features for embedded systems in Python. Work included implementing a multi-stage noise filtering pipeline, introducing adaptive low current filters with channel-specific thresholds managed via JSON, and enhancing calibration accuracy through per-chip ADC droop correction. Emphasis was placed on robust configuration management using YAML and JSON, with detailed documentation to support maintainability and onboarding. Each feature was integrated with careful attention to traceability and deterministic behavior, resulting in improved data quality and reliability for downstream analyses without explicit bug fixes during the period.

Nov 1, 2024In November 2024, the DUNE/ndlar_flow effort delivered key enhancements to the charge reconstruction pipeline. A Noise Filtering stage was implemented, integrating three filters (low current, correlated post-trigger, and hot pixel) to improve the quality of reconstructed hits. Hit-building was updated to include chip and channel IDs, enhancing traceability for downstream analyses, and the charge calculation was adjusted to use hardcoded conversion factors for consistent calibration across datasets. The changes were merged into develop from the feature-noise-filter work stream, consolidating the noise-filter improvements and aligning with prior work referenced by the commit history. Overall this month focused on robust feature delivery, code quality, and preparing the ground for higher-quality data products. No explicit bug fixes were documented in this month; the emphasis was on feature development, integration, and calibration groundwork.
