PROFILE
Mark Dalton
Worked on JeffersonLab/halld_recon to enhance monitoring and data visualization for physics experiments, focusing on both helicity and vertex analysis. Developed new C++ macros and plugins using ROOT to improve live dashboards, including robust plotting for helicity asymmetry across trigger bits and dynamic FCAL occupancy visualizations. Refactored histogram handling to display clear messages for missing data and improved y-axis scaling for small asymmetry values, increasing monitoring reliability. Introduced 2D vertex position histograms and refined canvas layouts, enabling more detailed and accurate online analysis. Emphasized C++ development, data analysis, and scientific computing to accelerate anomaly detection and improve data quality.

Jul 1, 2025July 2025: Delivered enhanced vertex monitoring visualization in JeffersonLab/halld_recon. Implemented new 2D histograms for vertex position (X-Z, Y-Z), refined the Z-vertex histogram, updated the canvas layout to accommodate the new plots, and tightened fill logic in the Process function to populate histograms with more specific vertex data. These changes improve online monitoring, data quality, and the speed of insights for target-vertex analyses.
