February 2026 — AliceO2: Focused on test coverage improvements and quality assurance for the TPCQC component. Delivered a new DCSPTemperature test to exercise DCSPTemperature logic within TPCQC, improving confidence in data quality checks. No major bugs fixed this month. Impact: reduces regression risk in temperature-related checks, supports faster, safer releases. Technologies/skills demonstrated: test automation, test harness integration, Git-based development, and CI/testing pipelines.

December 2025: Delivered Header-Only Redirect Entries Support for AliceO2 (AliceO2Group/AliceO2). Implemented the ability to create empty objects with headers when only headers are required, enabling proper handling of pure redirect entries. This feature was implemented via commit 99a77145c00dd215ddbc537b046173b1cbc13724 with message 'Add possibility for head only object'.

Month 2025-10: Delivered a key feature for the TPC Detector in AliceO2Group/AliceO2: user-configurable HBF integrity check. Introduced a new configuration flag 'check-incomplete-hbf' to enable or disable the incomplete HBF check, defaulting to silent to reduce noise while preserving the option to enable detailed validation when needed. This change enhances data processing flexibility, error reporting control, and reliability in production workflows.

September 2025 progress for AliceO2 (AliceO2Group/AliceO2). Delivered key TPC data handling and visualization improvements, enhanced traceability for DCS configuration, and tuned diagnostics to reduce log noise. Implementations span data type extensions, plotting controls, CCDB metadata, logging behavior, and voxel binning support in the painter, aligning with core reliability, performance, and data correctness objectives.

July 2025 monthly summary for AliceO2Group/O2DPG. Focused on data quality and reliability in the TPC processing path. Implemented an unconditional TPC common-mode correction for legacy CCDB data by forcing DigiMode to 2 (ZeroSuppressionCMCorr), ensuring correction is applied in all cases to prevent issues from legacy CMk values stored in CCDB for data predating a timestamp. This change reduces data quality risk in pre-timestamp data and strengthens the integrity of downstream analyses.

June 2025 monthly summary for AliceO2Group/AliceO2: Delivered Time Gain Calibration Enhancement introducing the use of TPC tracks from global track matches, improved reading of calibration data from files, and refactored the DCA calculation to optionally utilize global track information and DCAz, resulting in a more robust and flexible calibration process. This work enhances calibration robustness, flexibility, and data quality across runs, contributing to more accurate timing calibrations in physics analyses. No high-priority bugs fixed this month; focus was on feature delivery and code quality. Commit reference included below for traceability.

Monthly performance summary for 2025-03 highlighting key features delivered, major fixes, and overall impact across the O2DPG and AliceO2 repositories. Emphasis on business value, data quality, processing flexibility, and traceability through configuration enhancements, data filtering improvements, and streamlined I/O handling.

February 2025 performance summary for AliceO2Group/AliceO2 and AliceO2Group/O2DPG. The month delivered targeted features and robust bug fixes that improve data quality, calibration workflows, and MC analysis reproducibility, with strong traceability to commits and clear business value across production and DCS CCDB integrations. Key work focused on Monte Carlo usage controls, new track-selection criteria, enhanced logging, and calibration publishing pipelines.

January 2025 monthly summary focusing on TPC reconstruction quality, calibration accuracy, UI clarity, configuration resilience, and MC simulation support. Delivered four key items across AliceO2 and O2DPG with clear business value: improved calibration accuracy for Space Point calibration, enhanced event-display usability, robust configuration loading via CCDB redirects, and MC-time-gain support in TPC reconstruction.

December 2024 monthly summary for AliceO2Group/AliceO2. This month focused on data integrity improvements, enhanced reporting capabilities, and configuration flexibility to support better data validation, visualization, and configurable correction workflows.

Month: 2024-11 — Delivered three major features in AliceO2Group/AliceO2 focusing on configurability, data analysis granularity, and detector simulation accuracy. Key accomplishments include enabling runtime configuration for track interpolation via maxZ2X, enhancing Mapper with pad-category analysis for finer TPC data inspection, and introducing ExcludeFCGap to filter electrons between the IFC-OFC gap during processing, which reduces spurious readout entries and improves TPC simulation fidelity.

In October 2024, the team delivered a targeted calibration capability for the TPC detectors in the AliceO2 project, introducing Calibration Parameter Controls that limit and replace common mode k-values in high coupling regions. This enables more precise calibration values under challenging conditions, improving overall detector response accuracy and physics data quality.

September 2024 focused on improving detector data quality in AliceO2. Implemented CommonModeCorrection to compute common mode corrections for TPC data, reducing noise and improving accuracy; added a configurable IT fraction scaling parameter for OROCs in prepareITFiles to support flexible detector calibration and more accurate measurements. These changes strengthen calibration workflows and enhance data reliability for downstream physics analyses.
