Postdoctoral Appointee - Low Energy Nuclear Physics

Argonne National Laboratory

Lemont, IL

Job posting number: #7086753

Posted: October 7, 2021

Application Deadline: Open Until Filled

Job Description

An exceptional researcher is sought to lead the development and implementation of an automated optimization system for the delivery of secondary beams produced in-flight at the recently upgraded ATLAS In-Flight Facility. The successful candidate will join the low-energy nuclear physics group and coordinate with a small team of scientists and ATLAS Facility staff to complete the machine-learning (reinforcement learning) based optimization system. Various aspects of the project include, heavy-ion beam diagnostics hardware, working with accelerator components and control systems, and practical applications of optimization and machine learning techniques. The position also offers some portion of the candidates time for their own individually driven research interests.

The Low-Energy Nuclear Physics Research Group (LER) of the Physics Division at Argonne National Laboratory performs world-leading research in nuclear structure, nuclear astrophysics, fundamental symmetries, and nuclear data. The Group also manages and operates world-class detector systems as part of the ATLAS accelerator facility, a DOE supported national user facility for low-energy nuclear physics research. Information on the activities of the Group and the Division can be found at Any questions regarding the position should be directed to Dr. Calem R. Hoffman (

Position Requirements
