Plasma​/Ion Beam Research Scientist- Associate

Overview

Oak Ridge National Laboratory is searching for an Associate Plasma / Ion Beam Research Scientist to support the Enrichment Science and Engineering Division. The role focuses on advancing electromagnetic isotope separation technology and the plasma separation process, contributing to medical treatments, scientific research, and national security through isotopic products.

The Enrichment Science and Engineering Division (ESED) advances enrichment technologies and explores stable isotope production and applications — for national security, medical treatments, and scientific research. ESED oversees research, development, demonstration, and inventory management of stable isotopes.

The successful candidate will plan and conduct research and development to advance plasma science and technology for plasma-based enrichment systems, including Electromagnetic Isotope Separation (EMIS). This involves learning existing enrichment technologies and developing expertise over time while supporting the DOE Isotope Program and other DOE missions.

• Apply advanced concepts in plasma physics, ion beam transport, plasma chemistry, ion‑surface interactions, and related technologies to develop and deploy plasma‑based enrichment technologies, including EMIS.
• Use experimental data and simulations to understand the physics driving enrichment technology and identify optimization paths.
• Independently complete research to advance high‑mass ion source technology for flexibility across the periodic table while improving efficiency and stability.
• Conduct experiments in high‑current ion beam transport and isotope collection to optimize throughput and eliminate contamination sources.
• Collaborate with scientists to develop new isotope separation technologies to support the DOE Isotope Research Program.
• Develop into a subject matter expert for plasma‑based enrichment operations.
• Work closely with colleagues and safety professionals to ensure safe execution of work.
• Deliver ORNL's mission by aligning behaviors, priorities, and interactions with our core values of Impact, Integrity, Teamwork, Safety, and Service. Promote equal opportunity by fostering a respectful workplace.

• PhD in physics, engineering, chemistry, or related fields with relevant research experience.
• Ability to generate and execute new research ideas.
• Experience performing experimental research with plasma sources and/or ion beams.
• Demonstrated ability to work in collaborative, multidisciplinary environments.
• Experience working within R&D teams to solve complex problems.
• Excellent written and oral communication skills.
• Ability to function well in a fast‑paced research environment and adapt to changing needs.

• Experience with high‑current, low‑energy ion beam accelerators.
• Experience with electrostatic and magnetic ion beam optics.
• Experience with ion source design, testing, and modeling.
• Experience in plasma resonant heating using RF and/or microwave sources.
• Experience with plasma/ion transport in magnetic fields.
• Interest in developing high efficiency ion source technology for unique plasmas.
• Ability to translate physics understanding into experimental designs.
• Mechanical and electrical engineering skills in an R&D environment.
• Experience with Multiphysics simulation tools and collaborating with modeling researchers.
• Experience coupling experimental diagnostic data to simulation results.
• Experience in complex plasma chemistry.
• Experience in isotope enrichment science and engineering.

• Q Clearance:
  Ability to obtain and maintain a Department of Energy clearance is required.
• Workplace Substance Abuse (WSAP) testing: pre‑placement drug test and ongoing random drug testing program.
• Physical requirements:
  
  a pre‑hire physical will be required after offer.
• Visa sponsorship: not available for this position.
