Superconducting Radio-frequency SRF Engineer

Date: Sep 11, 2021

Location: Oak Ridge, TN, US, 37830

Company: Oak Ridge National Laboratory

Requisition Id 6207 

 

 

Overview: 

The Research Accelerator Division (RAD) within NScD invites applications for an SRF engineer in its SRF Group. The SNS SCL is the first accelerator that uses superconducting radio-frequency (SRF) technology for a pulsed proton machine and is now considered to be the world’s leading high-power SCL proton accelerator facility.



The SRF Group is responsible for safe, reliable and cost effective operation, maintenance, system engineering and improvement of the cryomodule for the SNS superconducting linear accelerator; for design, construction, commissioning, operation, system engineering and maintenance of the SRF test facilities at SNS; for focused R&Ds in the area of SRF and adanced laser techniques. The current SRF linac section accelerates the H- beam from 186 MeV 1 GeV via 81 SRF niobium cavities housed in 23 cryomodules. Additional 28 cavities housed in 7 cryomodules will be installed under the on-going proton power upgrade (PPU) project.

 

Major Duties and Responsibilities

  • Supports the operation of the SRF systems in support of the baseline reliability and safety objectives of the SNS.
  • Serves as the lead SRF engineer in diagnosing and troubleshooting the cryomodule operational issues.
  • Developes and implements advanced solutions for improved cryomodule performance leading to imporved availability of SRF linac.
  • Develops and excecutes the effort to maintain and improve critical SRF components such as the mechanical tuner systems in SNS cryomodules to meet the SRF and SNS operational metric goal.
  • Participates in maintenance and improvement of cryomodules and SRF test facilities.
  • Performs analysis of the cryomodule operation reliability to provide input for predictive cryomodule maintenance.
  • Develops and ensures availability of procedures, drawings, and other documentation required.
  • Supports SRF engineering for other current or future SRF projects or programs at the SNS facility or for other ORNL and DOE initiatives.
  • Participates in maintaining reliable cryomodule operation and responding to distruptive operational events, requiring flexibility in working hours to overcome unforeseen breakdowns.
  • Participates in scientific conferences, workshops, and meetings and publish results in the form of SNS technical notes and memos, workshop and conference proceedings, and scientific journals.
  • Ensures compliance with federal, state, and local environment, safety, health, and quality requirements.
  • Ensure compliance with Environment, Safety and Health (ES&H) and QA requirements.
  • 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

 

Basic Qualifications

  • BS in engineering, or a related technical field, and 5 or more years of applicable technical experience in design, construction, and operation of mechanical or electrical systems
  • Demonstrated knowledge of mechanical systems or electrical systems.
  • Excellent written and verbal communications skills
  • Knowledge of related safety issues, regulations, and safe practices

 

Preferred Qualifications

  • MS degree in engineering, or a related technical field
  • Knowledge of vacuum systems, high power RF systems or low level RF control systems.
  • Familiarity with accelerator systems and/or complex systems facility operations desired.
  • Working level proficiency in Creo CAD software
  • Proficient in mechanical and thermal engineering analysis
