Radiation Transport Graduate Research Assistant

What You Will Do

Do you want to use cutting edge simulation tools and your radiation transport expertise to solve challenges in the nuclear weapons arena? We are seeking post-master's students to join our team to help understand vexing problems and apply neutron, gamma, proton and electron transport expertise to help find solutions.
Work could span a broad range of Department of Energy & National Nuclear Security Administration missions, including modern and historic experimental diagnostics, intrinsic radiation, radiation detection and measurement, shielding design, nuclear reactor engineering, criticality safety, nuclear threat reduction and response, radiation health protection, nuclear weapons effects, and nuclear forensics. We are seeking candidates that have simulation and/or experimental backgrounds and interest in one or more of these topics. While most of our analysis involve the use of Monte Carlo radiation transport codes (especially MCNP and GEANT), we do value expertise with Discrete Ordinate methods. We also value experience with experiment design and radiation detection hardware, data collection, interpretation and analysis.

What You Need

Project Description 1: Work to expand the capabilities of the DRiFT detector response modelling software package with a focus on supporting inorganic scintillator arrays.
  • Desired Skills: C++, MCNP

Project Description 2: Work to simulate and compare to benchmark experimental data from HPGe detectors using MCNP and DRiFT detector response modelling software package.
  • Desired Skills: Python, MCNP

Minimum Job Requirements:
  • Technical Knowledge: You will need a technical background or advanced coursework in one or more of the following areas: historic experimental diagnostics, intrinsic radiation, radiation detection and measurement, nuclear reactor engineering, shielding design, criticality safety, nuclear threat reduction and response, radiation health protection, nuclear weapons effects, and/or nuclear forensics.
  • Radiation Transport Simulation Code: For this role you will need expertise in at least one radiation transport simulation code (e.g. MCNP6, GEANT, Attila/Attila4MC, PARTISN, etc).
  • Collaboration: Teamwork is essential to the success of our group. You will need to have demonstrated the ability to function effectively in a team environment with a willingness to learn new skills and be flexible in work assignments. This includes exhibiting professional conduct in interactions with co-workers and supervisors.


Desired Qualifications:

  • Programing
    It would be a plus if you had working knowledge of a scripting language and/or data analysis software (e.g. Matlab, root, python, etc).
  • Modeling
    It would be nice if you had experience modeling particle transport experiments and analysis/comparison of experimental data.


Education:Currently enrolled in an accredited graduate degree program in a science or engineering discipline with an overall GPA of 3.2 (out of 4.0) or higher. Must be enrolled in at least 6 semester credit hours (or full-time equivalent).

Work Location: The work location for this position is onsite and located in Los Alamos, NM. All work locations are at the discretion of management.
