Pacific Northwest National Laboratory Post Doc Research Associate - Nuclear Spectroscopy & Engineering in RICHLAND, Washington

Organization and Job ID

Job ID: 309283

Directorate: Energy and Environment

Division: Nuclear Science

Group: Nuclear Chemistry and Engineering

Job Description

A nuclear physicist and/or engineer is needed to assist with radiation spectroscopy counting operations in the RPL such as Hanford tank waste sample characterization, reactor dosimetry measurements like those regularly conducted for HFIR and ATR experiments, analyzing complex low-activity and high-activity samples in support of the International Monitoring System’s Radiation Laboratory and nuclear forensics, support fundamental nuclear data measurements probing neutron induced fission yields of actinides, develop algorithms and software for automated analysis of advanced radiation spectroscopy systems, and design and build detector arrays for improved detection sensitivities.

The candidate should have a strong working knowledge of radiation transport, C++/Python, and CERN’s ROOT & GEANT4 data analysis & simulation frameworks; these skills will be leveraged to test developed analysis tools against complex bulk fission product spectra acquired using continuous, prompt, and cyclic neutron activation techniques.

The candidate will be expected to publish fundamental nuclear data and support open-source development of advanced radiation spectroscopy The candidate will need to demonstrate proficiency conducting gamma spectroscopy and other nuclear counting techniques such as apha spectroscopy, beta counting, and liquid scintillation counting.

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.

Minimum overall GPA of 3.0 required


Preferred Qualifications

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

  • Ph.D. in Nuclear Science and/or Engineering or Physics, 3.5 GPA or higher is preferred

  • Candidates must have a strong background in their major field of study, the ability to work independently with little supervision, and an interest in working with others as part of an interdisciplinary team of researchers addressing challenges with national and international impact.

  • At least 2 years of experience in gamma spectroscopy

  • At least 2 years of experience with small scale software development is preferred

  • Experience in count-room operations and alpha/beta/gamma spectroscopy

  • Experience with software management using version tracking tools like GIT

  • Experience with CERN’s ROOT and GEANT4 data analysis and simulation software frameworks. Knowledge of MCNP in addition to CERN’s resources is preferred.

  • Operational experience with semiconductor and scintillation-based spectrometers

  • Strong oral and written communication skills.
