Major Duties and Responsibilities:

  • Provide accelerator operations support for the SNS and HFIR facilities operating 365/24/7, including occasional after hours call-in to achieve neutron production with >90% availability.
  • Contribute to the development and execution of the Proton Power Upgrade project.
  • Evaluate and upgrade existing pulsed power, power converter, magnet, power supply, kicker, and chopper systems to enhance performance, improve availability and address obsolescence issues.
  • Operate and upgrade multiple test stands to support continuous improvement development and testing activities.
  • Specify, develop, and procure subsystems and components.
  • Plan, manage, and execute maintenance and upgrade work.
