Job ID: 310223

Directorate: National Security

Division: Signatures Science & Technology

Group: Detection Physics

Job Description

PNNL is seeking an outstanding post-doctoral researcher to participate in the design and science of the nEXO neutrinoless double beta decay experiment as a member of the Detection Physics Group at PNNL. The appointee will play a leading role in the design and development of the liquid xenon TPC for nEXO and contribute to the overall scientific goals of the nEXO collaboration.

Candidates may have varied experience and focus. Areas of particular interest include noble liquids, time projection chambers, low radioactive background techniques, neutrino and dark matter physics, construction and running of prototype detectors, simulation and analysis of experimental data.

Applicants are expected to demonstrate unique technical strengths applicable to the above research efforts and present a compelling vision for their contribution to this research program. Excellent communication and presentation skills are required, and a demonstrated ability to publish completed research is a key desired attribute.

Beyond the scope of neutrinoless double beta decay research, the selected researcher may also contribute to the Detection Physics Group’s applied radiation detection programs. The selected researcher will assist with the cross-pollination of new methods and technologies in radiation detection relevant to both basic and applied research programs. This cross-disciplinary and entrepreneurial environment is a strength the Detection Physics Group has fostered and maintained over multiple decades.

Minimum Qualifications

Candidates must have received a PhD within the past five years (60 months) or within the next 8 months from an accredited college or university.

Preferred Qualifications

  • Technical Expertise: General knowledge of low radioactivity detector systems, or other technical skills with respect to these detectors such as cryogenics and vacuum systems is desired. Experience with or knowledge of noble liquid systems and time projection chambers is preferred.

  • Familiarity and prior experience with particle simulations codes such as Geant4, MCNP, etc, analysis software such as ROOT, as well as engineering software such as Solidworks and COMSOL is advantageous.

  • Level of Responsibility: Personal contributor to detector design and development, close coordination within the nEXO collaboration, and presentation and publication of results within the broader scientific community.

  • Breadth of Relevant Technical Knowledge: Neutrinoless double beta decay or related nuclear and particle physics

Preferred Education

  • Ph.D. in nuclear or particle physics, astrophysics, or a related field. Cumulative GPA of 3.5 or higher preferred.
