Introduction

The postdoctoral associate will work the neutronics team to develop and implement an instrumented liquid hydrogen moderator vessel intended to demonstrate the neutronics performance and kinetics of ortho- and para-hydrogen subjected to radiolysis.

Description of Institution

The Neutron Sciences Directorate (NScD) at Oak Ridge National Laboratory (ORNL) operates the High Flux Isotope Reactor (HFIR), the United States’ highest flux reactor based neutron source, and the Spallation Neutron Source (SNS), the world’s most intense pulsed accelerator based neutron source. Together these facilities operate 30 instruments for neutron scattering research, each year carrying out in excess of 1,000 experiments in the physical, chemical, materials, biological and medical sciences. HFIR also provides unique facilities for isotope production and neutron irradiation. To learn more about Neutron Sciences at ORNL go to: http://neutrons.ornl.gov.

Job description

Major Duties/Responsibilities

  • The selected applicant will implement non-neutron-based techniques for assessing the ortho-para distribution in a liquid hydrogen system under neutron irradiation.
  • The selected applicant will play a major role in the specification and implementation of a volume-moderator demonstration setup at a moderator test facility.
  • The selected applicant will participate in the design and construction of a prototypic moderator demonstration facility.
  • Displays ES&H understanding and discipline that leads to outstanding safety performance. Maintains the highest ethical and professional standards of performance and operates in accordance with these standards. Embodies ORNL values to be the best in everything we do, guided by shared values that exemplify concern for people and working together to meet challenging goals.
  • Ensure compliance with environment, safety, health and quality program requirements.
  • Maintain strong commitment to the implementation and perpetuation of values and ethics.
  • Physical requirements for this job include the use of hand and eye protection gear, kneeling, sitting for extended periods of time, working with low temperature sample environment equipment, and possible exposure to ionization radiation normally associated with operation of neutron scattering instruments for scientific research.
