Working/Functional Title

High Power Targetry Scientist

Position Summary

Major Responsibilities

-Charge Strippers (80%)

• Support FRIB operations by maintaining liquid lithium and carbon charge strippers to ensure an operational state.
• Provide technical support on the charge strippers during FRIB operations
• Lead implementation of improvements of the charge strippers. This includes conceptual designs of improvements, R&Ds, support of detailed designs, and validations. Improvements are, but are not limited to,
  • Liquid lithium charge stripper
    • Producing a thicker and more uniform liquid lithium film;
    • Minimizing the splashing of liquid lithium in the vacuum chamber.
    • The scope of improvements includes the subsystems of the strippers (e.g. vacuum and/or argon subsystems of the liquid lithium charge stripper)
  • Carbon foil charge stripper
    • Exploring carbon foils that have longer lifetimes than the one currently in operation, which includes necessary R&Ds
• Conduct scientific research that could break through the current technical limitations of the charge strippers. This also includes contributions to understanding the physics behind charge exchange between beams and charge-stripping media

-Target and Beam Dump (15%)

• Support the production target and beam dump systems improvements through discussions, simulations, analyses, and testing

-Performs other duties as required or assigned, which are reasonably within the scope of the duties in this job classification. (5%)

Knowledge, Skills, and Abilities (KSAs)

• Thorough knowledge of liquid and carbon charge strippers
• Thorough knowledge of target and beam dump systems
• Proficient in maintaining, servicing, and repairing liquid and carbon charge strippers and target beam dump systems using the appropriate and necessary equipment
• Knowledge of industry-safe work practices in the field.
• Ability to communicate effectively and credibly, both verbally and in writing, with audiences at all management levels.
• Ability to problem-solve and demonstrate sound critical thinking skills
• Ability to work independently, within a team, and in an extensive collaboration
