Instrument Engineer, STS

Date: Feb 19, 2021

Location: Oak Ridge, TN, US, 37831

Company: Oak Ridge National Laboratory

Requisition Id 4911 

Oak Ridge National Laboratory (ORNL) is seeking an Instrument Engineer for the Second Target Station (STS) project. The STS is a >$1Billion, Department of Energy project to be constructed over the next decade at the ORNL Spallation Neutron Source (SNS).  The STS will provide wholly new capabilities for the study of a broad range of materials with neutron scattering and support thousands of users from the physical, materials, and applied sciences as well as industry. The science capabilities provided by the instrument suite at the STS will complement those of the two existing DOE Office of Science neutron scattering user facilities at ORNL, the First Target Station (FTS) of the SNS and the High Flux Isotope Reactor (HFIR). The STS will deliver the highest peak brightness of cold neutrons in the world, which together with advances in neutron optics, instrumentation, and detectors, will ensure US leadership in neutron scattering for decades to come. The STS will be capable of supporting 22 individual neutron scattering instruments (beamlines), each of which transports neutrons from the source to a shielded end station which houses a user-provided sample along with a suite of detectors. Each instrument has unique requirements and incorporates custom configurations of neutron optics, choppers, detectors, sample environment and shielding.

The STS Instrument Systems Group is responsible for the design and development of instruments for the STS Project.

An Engineer in STS Instrument Systems Engineering is responsible for designing components and subsystems of a neutron scattering instrument, or beamline. STS Instrument Engineering uses a systems engineering approach to beamline design, and as such, the STS Instrument Engineer will work within a in specialized engineering team to design components for a beamline in such a way as to ensure each instrument’s scientific objectives are met within the cost, schedule and scope expectations of our DOE sponsor. The Instrument Engineer will work alongside other instrument engineers and scientists. The Instrument Engineer may be responsible for overseeing the procurement and fabrication of neutron instrument components. The Instrument Engineer may design, develop and provide engineering support for neutron choppers, vacuum vessels, pressure vessels, equipment positioning devices, personnel safety systems, neutron shielding, biological shielding, optical components as well as other specialized devices. These components are often first of a kind or one of a kind.

The ideal candidate will have experience as an Engineer at a neutron scattering facility or synchrotron, or in industry. Instrument Engineers typically (but not always) have a background in machine design.
