Oak Ridge TN, USA

The Beam Science and Technology Group is seeking a strong physicist to maintain and develop the intellectual understanding of the SNS accelerator beam, required to sustain stable beam operations and to increase beam power while minimizing beam loss. This is an exciting opportunity to utilize the SNS accelerator to further the understanding of high intensity beam physics. In this role you will perform research on topics including (but not limited to) beam dynamics in the normal and the superconducting parts of the SNS linac, the SNS accumulator ring and transport lines, and the Beam Test Facility (BTF). You will conceive and pursue beam-based experiments, and develop analytical and computer models to simulate and understand beam effects. You will actively participate in the team’s activities and interface with other accelerator physics team members, with the Beam Instrumentation Team, and with the Controls and Operations Groups.

The Spallation Neutron Source (SNS) is the world’s most intense pulsed accelerator-based neutron source. The SNS is part of the Neutron Sciences Directorate (NScD) at Oak Ridge National Laboratory (ORNL), which also contains the High Flux Isotope Reactor (HFIR), the United States’ highest flux reactor-based neutron source. Together these facilities operate 30 instruments for neutron scattering research, each year carrying out in excess of 1,000 experiments in the physical, chemical, materials, biological and medical sciences. HFIR also provides unique facilities for isotope production and neutron irradiation. To learn more about Neutron Sciences at ORNL go to: http://neutrons.ornl.gov

Major Duties and Responsibilities:
• Develops beam simulation models or tools to help understand high intensity beam physics.
• Diagnose and remedy machine and beam dynamics issues that are not understood.
• Develop lines of inquiry to understand or improve aspects of the SNS accelerator beam.
• Develop beam study plans, and participate in shifts to pursue the general lines of inquiry.
• Participate in scientific conferences, workshops, meetings and publishes results in the form of SNS technical notes and memos, workshop and conference proceedings, and scientific journals.
• Participate with other team members in developing goals, resource plans, and policies for the Team and the Group.
• Assist team leader in coordinating the work of graduate students in the team.
• Ensures compliance with environment, safety, health, and quality program requirements including ISMS.
• The SNS and HFIR facilities are in operation 24 hours per day and 7 days a week year round. You may be occasionally required to support users and/or facilities during off hours or weekends.
• As a member of the ORNL scientific community, you will be expected to commit to ORNL’s Research Code of Conduct. Our full code of conduct, and a statement by the Lab Director’s office can be found here: https://www.ornl.gov/content/research-integrity

• Appointments will initially be for 24 months with a possibility of an extension of up to 12 months
• Initial appointments and extensions are subject to performance and availability of funding
