PROFILE
Zihlmann
Over a three-month period, Zihlmann developed and delivered three targeted features for the JeffersonLab/halld_recon repository, focusing on data acquisition, calibration, and error handling using C++. He implemented log-verbosity controls to limit truncated FDC/CDC data warnings, reducing log noise and improving monitoring reliability. For detector timing synchronization, he introduced 2D histograms to visualize timing differences across calorimeters, supporting more accurate cross-calibration and downstream physics analysis. Additionally, Zihlmann enhanced error reporting in data parsing by adding detailed exception context, streamlining debugging and root-cause analysis. His work demonstrated depth in data analysis, log management, and robust software development practices.

Jul 1, 2025July 2025 (2025-07) monthly summary for JeffersonLab/halld_recon focused on improving data pipeline observability. Key feature delivered: Enhanced error reporting for data parsing in DEVIOWorkerThread. This enhancement adds descriptive context to parsing exceptions, including function names and specific error details, to support faster root-cause analysis and more reliable data ingestion. The change is captured in commit f1dc9b5a7125b049f7300e51b7763642563b7ad1 with the message 'add more verbose information when exception is thrown.'

Jun 1, 2025June 2025 monthly summary for JeffersonLab/halld_recon: Delivered a new Detector Timing Synchronization feature by introducing 2D histograms to visualize timing differences between TOF timing and RF timing, correlated with BCAL/FCAL/ECAL, and added code to fill the ECAL timing minus RF histogram for consistent cross-calibration across calorimeters. This work lays the foundation for improved timing calibration across detectors and supports downstream analyses.

Apr 1, 2025April 2025 (2025-04) monthly summary for JeffersonLab/halld_recon: Implemented targeted log-verbosity control for truncated FDC/CDC data warnings to reduce log noise while preserving critical data integrity signals. Introduced per-type counters to emit only the first 10 instances, with the worker updated to suppress further warnings after the 10th occurrence and an explicit suppression message. This work improves operator experience, stability of nightly runs, and monitoring dashboards, enabling faster issue detection without overwhelming log streams. Notable commits include: 1f1ce1448f2808ecb4584bdd9cd7977b54ad028f and e6a5ffc74e7b07cd27e1c61ed8cd36e858f1564f.
