Title: Post Doctoral Fellow Accelerate Nb3Sn
Newport News, Virginia, US, 23606
At Jefferson Lab, you’ll champion cutting-edge science and operational excellence while shaping the future of discovery. Join us and make your mark – where excellence meets purpose, and great minds truly matter.
The good-faith pay range for this role is $65,600 - $90,300 per year. Actual compensation may vary and may be above the posted range based on factors such as a candidate's skills, experience, education, certifications, and work location.
JSA will not sponsor an H1B visa for this position.
What your job will be like:
The JLab Superconducting radio frequency (SRF) research department seeks a Postdoctoral Research Associate to take part in its thin film programs and particularly focus on developing the deposition of Nb3Sn on copper (Cu) primarily in the framework of compact accelerators.
With guidance, the Post-doctoral Fellow will conduct research on A15 superconducting materials and associated buffer layer deposition to prevent Cu diffusion for application to compact accelerators. In particular, the incumbent is responsible for developing and optimizing a method to achieve the sought-after phases and structures by leveraging energetics to enable deposition of Nb3Sn at lower temperatures than usually possible with conventional methods. These activities also include working with surface analytical tools like SEM combined with EBSD and EDS, TEM/EELS, SIMS, and XPS. The incumbent will also work closely with the principal investigator, staff and graduate students to conduct RF evaluation at cryogenic temperatures of SRF film structures coated on QPR samples to evaluate results, which guide the optimization of deposition methods, leading to implementation of the technology on elliptical single-cell cavities, and to write reports in the form of technical notes, conference proceedings and/or peer reviewed journals.
In this job you will:
- Assist in deposition of Nb3Sn thin film and structures, characterize samples and devices using microscopes, physical property system and magnetometry setups, and prepare and mount samples for these experiments.
- Participate in analyzing the microstructure and properties of superconducting films and structures generated within the SRF S&T Department
- Participate in the installation and commissioning of an upcoming cylindrical magnetron deposition setup
- Determine solutions to technical problems by reviewing scientific and technical literature and simulation methodologies designing and executing experiments to support research. Conduct, analyze, and present data.
- Presents scientific conclusions at internal and external meetings, in technotes, proceedings and/or peer-reviewed journals.
- Collaborate with scientists, engineers, and technicians to accomplish research goals.
Experience
- Required: Strong background in surface & thin film science with experience in one or more of the techniques mentioned above and be willing to use experimental background to crossover into the field of accelerator physics and microelectronics.
- Required: Experience with cryogenic and/or RF measurements.
- Required: Experience with experimental setups for superconducting measurements
- Preferred: Experience with thin film deposition techniques.
- Preferred: Experience in calculations and/or simulations regarding the particle interactions in matter, especially experience with MatLab, COMSOL or PIC/MC software.
Education
- Required: Ph.D. Physics, Applied Physics, Superconducting RF, Material Science. etc.
Experience and Education Exchange
Knowledge, Skills, and Abilities
- Knowledge in materials science & engineering, superconductivity, rf is desired.
