AI4HallC Working Group Meeting

Friday Dec 16, 2022, 3:00 PM → 5:00 PM US/Eastern

Mark Jones (Jefferson Lab), Tanja Horn (Catholic University of America)

AI/ML has become ubiquitous in nuclear physics in the last few years and new possibilities have been emerging. This is an opportune time for Hall C to take advantage of these developments in computing technologies and statistical methods and define its path forward. The main goal of the Hall C AI/ML Working Group will be to provide a forum for discussion for anyone interested in defining this path, exploring possible applications of AI/ML in Hall C, and connecting to data scientists.

 

During the 11/18/22 kick-off meeting the role of Hall C in global AI/ML efforts at JLab was discussed. Hall C is the precision measurements hall at JLab providing pillars of measurements to constrain physics quantities like Parton Distribution Function and Parton Distribution Amplitudes. Because of this Hall C has a unique role and very different equipment and operation requirements from the other halls, e.g., Hall C operation has multiple subsystems (beam, spectrometer, target) whose drifts/changes must be monitored as they all directly impact performance and physics output of Hall C. Two major needs were identified:

• Operations composed of optics, data preparation, and equipment and operation

• Uncertainty quantification for global physics analysis, e.g., PDF/PDA

The goal of this second meeting is to follow up on the two action items: 1) The highest priority is to define the parameters for the high-level Hall C operations (optics, equipment, operation) and therefore for Hall C as precision hall. Once parameters are defined need to collect data for Hall C, e.g., beam positions, magnet parameters, target. 2) In parallel, the uncertainties that come in to high level global physics analysis in Hall C have to be defined.
