Internship Accelerator Physics Jobs (NOW HIRING)

What You Will Do
The Adaptive Machine Learning team is seeking a post-bachelor student in computational physics. The team is part of the Accelerator Operations and Technology (AOT) Division within the Instrumentation and Control (IC) Group. Our work focuses on research and development to improve accelerator operations through machine learning, control theory, and physics-based simulation. Beyond research and development, the team supports the implementation of practical, operationally relevant solutions for the Los Alamos Neutron Science Center (LANSCE).
The successful candidate will contribute to the computational aspects of this research. In particular, the candidate will support efforts to improve accelerator optimization and tuning by modernizing existing software, applying physics-constrained machine learning, or developing differentiable physics simulations.
The position is for one year, renewable for a second year.
Please apply before July 15th, 2026.
