Postdoctoral Research Associate

The Facility for Rare Isotope Beams (FRIB) will be a new scientific user facility for nuclear science, funded by the Department of Energy Office of Science (DOE-SC), Michigan State University (MSU), and the State of Michigan. Under construction on campus and to be operated by MSU, FRIB will provide intense beams of rare isotopes (that is, short-lived nuclei not normally found on Earth). FRIB will enable scientists to make discoveries about the properties of these rare isotopes in order to better understand the physics of nuclei, nuclear astrophysics, fundamental interactions, and applications for society. 

This position affords an exciting opportunity to become part of the world-class FRIB Project, and to get in on the ground floor of an emerging scientific user facility that will expand nuclear science into a whole new realm of possibility.

Position overview

FRIB is searching for a Postdoctoral Research Associate to join the FRIB Project Team. The successful candidate will be responsible for design, develop, and implement various processes, components and instrumentations that will improve the performance of superconducting rf cavities and cryomodules.

Major position responsibilities

  • Assemble niobium cavities and RF components in clean room and prepare for RF tests
  • Perform cryogenic tests of niobium cavities, RF components and cryomodules
  • Perform RF power coupler cleaning, conditioning, and testing
  • Develop and/or improve the SRF components and processes that will improve the performance and yield of niobium cavity during production, particularly reducing the cavity multipacting in a cryomodule
  • Develop and/or improve the instrumentations that will help identify cavity performance limitations such as optical inspection tool, temperature mapping sensors, second sound detector, and apply relevant techniques to a cryomodule
  • Assemble cryomodules for FRIB production
  • Develop and/or improve the cryomodule components and procedures to improve the reliability and performance of a cryomodule
  • Involve in SRF development of critical components (cavity, coupler, and tuner) for FRIB upgrade cryomodules



  • PhD in physics or closely related field
  • Demonstrated knowledge of Superconducting RF technology
  • Excellent verbal, presentation, and technical report writing skills
  • Efficient collaboration within project teams
  • Ability to work with export-controlled items


  • Experience with class 100 clean room
  • Experience with cryogenic instrumentation and high power RF
  • Experience in engineering software such as labview, and matlab
  • Experience in electromagnetic software equivalent to CST Microwave Studio, Ansys.


MSU employees receive excellent benefits including health/dental plans, a generous retirement plan, and educational assistance.

About FRIB and MSU, and the East Lansing community

FRIB is currently under construction and baselined at a total project cost of $730 million. Upon start of user operation in 2022, FRIB will enable scientists to make discoveries about the properties of rare isotopes in order to better understand the physics of nuclei, nuclear astrophysics, fundamental interactions, and applications of rare isotopes to benefit society.

MSU is one of the largest university campuses in the United States with a beautiful campus of 5,000 tree-filled acres. It has 17 degree-granting colleges and is a center for academic and research activities as well as the arts and athletics.

The campus sits between Lansing (Michigan’s capital city) and East Lansing. The Lansing area has a population of 460,000 and offers lovely suburban areas, loft condos and other urban living opportunities as well as easy-to-get-to rural areas. A symphony orchestra, excellent health care, many community and professional theatres, rivers, lakes, outdoor festivals, close access to large cities and Lake Michigan make for a near-perfect living environment.

MSU is an affirmative action, equal opportunity employer.
