What Your Job Will Be LikeThe X-ray Diagnostics and Experimental Systems group is seeking a highly motivated and innovative scientist to lead the development of advanced x-ray imaging and spectroscopy instrumentation for experiments conducted on the Z Machine the world's most powerful pulsed-power facility.
This position offers a unique opportunity to contribute to cutting-edge research in high-energy-density (HED) physics, working closely with a multidisciplinary team of scientists, engineers, and technologists. This position will involve close collaboration across several organizations within the Pulsed Power Sciences Center at Sandia to lead the development of new x-ray imaging and spectroscopic diagnostics aimed at addressing key questions about the hot plasmas generated with the Z-machine, as well maintain our Center's leadership in advancing x-ray instrumentation across the high-energy-density (HED) physics community.
On any given day, you may be called to:
- Lead the design, development, and deployment of novel x-ray diagnostics for Z Machine experiments.
- Analyze x-ray imaging and spectroscopic data to extract physical insights into hot plasma behavior.
- Develop and apply calibration techniques for existing and new x-ray diagnostics
- Troubleshoot deployed systems and ensure the delivery of high-quality experimental data.
- Collaborate across organizations within the Pulsed Power Sciences Center and with external partners.
- Present your research at national and international conferences.
- Publish findings in peer-reviewed journals.
- Travel occasionally (2 - 3 weeks per year) for collaboration or conference participation.
Due to the nature of the work, the selected applicant must be able to work onsite.
Salary Range$117,500 - $235,700
* Salary range is estimated, and actual salary will be determined after consideration of the selected candidate's experience and qualifications, and application of any approved geographic salary differential.
Qualifications We Require- A Bachelor's degree in a relevant discipline and five (5) years of directly relevant experience, or an equivalent combination of directly relevant education and engineering or scientific experience that demonstrates the knowledge, skills, and ability to perform independent research and development.
- Ability to obtain and maintain a DOE Q clearance.
The ideal R&D S&E Physics candidate for Sandia National Laboratories will in addition possess the following:
- Graduate degree in Physics or a highly related field where an independent research project was a graduation requirement (e.g., independent project, thesis, or dissertation).
- Experience preparing research for dissemination through presentations at national conferences and peer-reviewed publications in top journals.
- Demonstrated leadership abilities of both projects and teams and the ability to work in loosely defined areas with minimal direction while maintaining vision for the overall mission.
- Strong verbal and written communication skills, ability to work effectively in multidisciplinary teams.
Also, for this posting we are seeking individuals with the following experience:
- PhD in plasma physics, electrical engineering, nuclear physics or related STEM field.
- Experience in designing and fielding x-ray imaging and/or x-ray spectroscopy instrumentation for 1 to 100 keV
- Experience as principal investigator for experimental campaigns on small-scale, university HED facilities or large facilities such as Omega, Z, or NIF.
- Experience with calibrating and analyzing x-ray spectral data.
- Knowledge of atomic physics in hot plasmas.
- Strong publication and presentation record.
- Ability to collaborate across a broad range of organizations such as universities, private industry, and other national laboratories x-rays.
