May 2025 monthly summary for DUNE/dunesw. Delivered a key feature enabling enhanced low-energy trigger studies by lowering the E_bin_lefts threshold to 2 MeV through two FCL configuration updates, expanding the sensitivity and scope of trigger performance evaluations. This work improves data quality for low-energy events and provides traceable configuration changes in the trigger analysis pipeline.

In April 2025, completed substantial configuration refactors and standardizations across DUNE simulation repos (dunesw and dunesim), enabling more maintainable and scalable simulation workflows. Key gains include spectrum-based organization of SN configs, standardized particle gun configurations for trigger production, and MARLEY configuration overhaul with expanded spectra and updated vertex definitions for the VD region.

March 2025 performance summary focusing on centralized configuration, parameter standardization, and configuration hygiene across the DUNE software stack. Key outcomes include establishing a single source of truth for detector parameters, standardizing ADC/Nbit handling across simulation and reconstruction tools, and cleaning up configuration parsing to reduce noise and maintenance overhead. These changes pave the way for more reliable deployments, easier onboarding, and consistent signal processing across detector configurations. Key features delivered: - Centralized detector configuration with dune/params.jsonnet (DUNE/dunereco): introduced dune/ as entry point and unified imports to standardize ADC resolution and elecGain across all detectors. - Standardized configuration parameters for signal shaping and ADC depth (DUNE/dunecore, DUNE/dunesim): added standard Nbit and gain values; updated ADC tools to reference Nbit_standard from signalservices_dune.fcl. - Testing configuration cleanup for WIBEth3 TPC decoding tests (DUNE/duneprototypes): removed outdated test configuration to reduce maintenance burden. Major bugs fixed: - Bug fixes and cleanup for configuration parsing and syntax (DUNE/dunereco): removed stray json files, fixed syntax issues, and ensured Nbit/elecGain are sourced solely from the unified params.jsonnet. Overall impact and accomplishments: - Improved reliability, maintainability, and cross-repo consistency by consolidating configuration sources and standardizing bit-depth handling. - Reduced risk of misconfiguration across detector configurations, enabling faster onboarding and more predictable simulation/reconstruction results. Technologies/skills demonstrated: - Jsonnet-based configuration and modular parameter management (dune/params.jsonnet). - FCL-based parameter referencing and cross-repo integration (signalservices_dune.fcl). - Configuration hygiene and commit-level hygiene (removal of deprecated files, syntax fixes).

January 2025 monthly performance: Delivered two core features to enhance physics fidelity and deployment readiness. No major bugs fixed this month. Impact includes enabling ES interactions in nue_spectrum simulations and introducing a new dune10kt geometry via larg4detector, enabling faster setup for fdhd studies and improved validation capabilities. Demonstrated proficiency in FCL configuration, ES.react integration, and GDML-based geometry management with clear commit traceability.
