The Superconducting Linac (SCL) Systems Group Engineer will lead, supervise or support the SCL Systems group’s efforts within the SCL Systems Group in the Research Accelerator Division. The group is responsible for safe, reliable and cost effective operation, maintenance, and improvement of the cryomodules, cryogenic plant, and cryogenic distribution systems that comprise the SNS superconducting linear accelerator; for design, construction, commissioning, operation and maintenance of SRF/Cryogenic test facilities at SNS; for research, engineering and development of SRF/Cryogenic parts or systems for the SNS machine upgrade or in collaboration with partners; for system engineering associated with the helium components of the cryogenic moderator system that supports the SNS neutron production target; and for providing cryogenic engineering and design efforts in support of other cryogenic systems that may be installed at the SNS facility.

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 more than 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.
