PROFILE
Gadorlhiac
Over five months, contributed to the slac-lcls/lcls2 repository by developing and enhancing detector interfaces, data processing pipelines, and configuration management tools. Delivered features such as hot pixel metric retrieval for the Jungfrau detector, a raw data interface for the ePixUHR3x2 detector, and memory-leak mitigation using weak references and registry patterns. Addressed automation reliability by implementing conditional recording state management and improved calibration deployment with environment-specific database support. Leveraged Python, object-oriented programming, and software design patterns to streamline data acquisition, conversion, and analysis workflows, resulting in more robust, maintainable, and scalable systems for high-throughput experimental data environments.

1 Commits • 1 Features
Apr 1, 2026April 2026: Delivered a new psana interface for the ePixUHR3x2 detector in slac-lcls/lcls2, enabling retrieval, unpacking, and reshaping of raw data. This includes dedicated unpacking and reshaping utilities to streamline raw data handling and prepare data for downstream analysis. No major bugs fixed this month; stability work focused on validating the new interface and its integration with existing psana workflows. Overall impact: enhances data accessibility and processing throughput for high-rate experiments, strengthening data-driven research capabilities. Technologies demonstrated: psana framework, detector data interfaces, raw data unpacking/reshaping utilities, Python utilities, version control and code review practices.

Jul 1, 2025July 2025 (slac-lcls/lcls2): Delivered stability improvements and configuration enhancements for pedestal scans in the LCLS2 data processing stack. Implemented memory-leak mitigation for calibration constants and detector instances using weak references and a registry pattern, and added configurable run_type for pedestal scans with a default of DARK. These changes improve memory stability for long-running workflows, data integrity across runs, and provide clearer, more flexible scan configurations. Commit traces include a1bbde1fa43337c7d58eeef2513b10f7eed69982 and 3a1c25675ae73dbacfff42acb952b491d31d6b02 for traceability.

Jun 1, 2025June 2025: Reliability fix in slac-lcls/lcls2 to auto-disable recording after a scan completes when recording was requested. Implemented a conditional in config_scan_base to disable recording at scan end, ensuring correct recording state and cleaner data capture. Commit cc8e13ea866b78a8d790e5f3d10b51fa5e5fd4b4. Impact: reduces stale recordings, lowers operator overhead, and improves automation reliability for scan workflows. Technologies demonstrated: Python/config tooling, conditional logic, Git/version control, and targeted debugging in instrument control software.
