April 2025 monthly performance summary for DUNE/waffles focusing on NP02 onsite analysis capabilities. Overview: Released a targeted onsite analysis tool for NP02 detectors, enabling grid-based visualization of waveforms, sigma histograms, and FFTs. The work encompassed parameter handling, data ingestion, analysis execution, and output generation to streamline onsite performance assessment. Key achievements: - NP02 Onsite Analysis Tool: Waveforms, Sigma Histograms, and FFT Visualization delivered for NP02 onsite operations (repository: DUNE/waffles). - Grid-based visualization layout implemented to enable quick, side-by-side inspection of waveform plots, histograms, and FFT results. - End-to-end capability developed: input parameter handling, data ingestion, analysis execution, and output generation to support rapid onsite decision making. - Traceability through commit: f10542f44c2124b74c68a253998e712001705231 (Adding a quick NP02 analysis (waveforms plots, sigma histograms and FFT in a grid) for onsite operation, and some tools for this purpose). Impact and accomplishments: - Accelerated onsite performance assessment for NP02 detectors, reducing analysis time and enabling faster operational decisions. - Strengthened data processing workflow with structured parameterization and output artifacts suitable for onsite reporting. Technologies and skills demonstrated: - Signal processing concepts: FFT visualization, sigma histograms, waveform analysis. - Data ingestion, parameter handling, and end-to-end analytics pipeline. - Grid-based visualization design for efficient onsite evaluation. - Version control traceability and focused feature delivery to support business value.
