Oak Ridge National Laboratory
Oak Ridge National Laboratory

Job Location: Oak Ridge, TN

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 for more than 3,000 visiting scientists. HFIR also provides unique facilities for isotope production and neutron irradiation. To learn more about Neutron Sciences at ORNL go to: Purpose: The Neutron Scattering Directorate at Oak Ridge National Laboratory (ORNL) invites applications for a Postdoctoral Research Associate with strong experience and expertise in scattering techniques for materials studies and interests in Monte Carlo Ray tracing and high performance computing techniques as well as neutron sample environments. It will comprise a set of activities to reduce background for high pressure environments through automated design and 3D printing of collimation. This project is collaboration between the Neutron Scattering Division (NSD), the Neutron Technologies Division (NTD), Energy & Transportation Science Division (ETSD) at ORNL and it benefits from interactions with the instrument teams in the Neutron Science Directorate (NScD).

Major Duties/Responsibilities:
In this role you will help develop a work flow for optimizing collimator design using Monte Carlo Ray tracing and high performance computing (HPC). You will apply the design in the NScD high pressure research program. We are seeking self-starters, willing to develop expertise in neutron instrumentation, optimization techniques on HPC, work on high pressure environments and high pressure physics problems, statistical analysis, and optimization techniques. This is an opportunity for you to join an interdisciplinary research team between NSD, NTD, and ETSD with expertise in Monte-Carlo neutron ray-tracing simulations, optimization, high-performance computing, neutron instrumentation, neutron high pressure environments and additive manufacturing techniques. You will be involved with workflow and algorithm development, scientific data analysis, neutron pressure experiments, publishing results, and developing software.Other Responsibilities include:* Develop a workflow to optimize Monte Carlo ray tracing simulations of Collimation for high pressure environments and provide the file to create an additive manufactured part.* Perform neutron scattering experiments in the collimated pressure environments and analyze data taking advantage of the collimation.* Responsible for presenting and reporting research results and publishing scientific results in peer-reviewed journals in a timely manner* Ensures compliance with environment, safety, health and quality program requirements* You will be expected to commit to ORNL's Research Code of Conduct by holding yourself and others to the highest scientific, professional, and ethical standards in a manner that fosters mutual respect and enhances the reputation of the individual researcher, his/her colleagues, and the Oak Ridge National Laboratory in its mission to address the Department of Energy's and the nation's scientific and technical challenges.

Qualifications Required:
* A PhD completed within the last 5 years in physics, applied physics, applied math, material science, chemistry, or other relevant fields from an accredited institution.* An excellent record of productive and creative research demonstrated by publications in peer-reviewed journals* Desire to learn and adopt newtools and technologies* Candidates should be self-motivated, have good interpersonal, communication and presentation skills and a demonstrated ability to interact effectively with colleagues at all levels. The ability to work as a member of a multi-disciplinary team is a critical asset.* Excellent written and oral communication skills and the ability to communicate in English to an international scientific audience* Motivated and safety conscious* Ability to set priorities, multi-task and adapt to ever changing needs with the proven ability to function well in a fast-paced environment* Ability to work with a measure of autonomy and a willingness to participate creatively in a collaborative team environment* Ability to work on multiple tasks in a limited amount of time and to independently set priorities to accomplish multiple tasks to meet deadlines* Applicants must have received their degree within five years of the date of application and must complete all degree requirements before starting their appointment. Certain exceptions may be considered. Appointments will initially be for 24 months with a possibility of an extension of up to 12 months depending on funding and performance.* This position is a temporary, full-time assignment of 24 months with a possibility of an extension to 36 months, depending on the funding situation. Initial appointments and extensions are subject to performance and availability of funding.Qualifications Desired:* Expertise in analysis of scattering data * Experience with neutron diffractometers* Scientific computing skills such as optimization or Monte Carlo ray tracing simulation* Knowledge and experience in one or more programming languages such as: Python, C++, C, Fortran, and Unix/Shell* Experience with high pressure environmentsPublication List and Letters of Reference:Please provide a list of publications when applying for this position. A minimum of two letters of reference are required and can be uploaded to your profile or emailed directly to THIS EMAIL . Please include the title of the position in the subject line.

Work Directions and Interfaces:
