Cryogenic Engineer

Position Description

The NSLS-II RF Group designs, fabricates, operates, and maintains multiple high power Radio Frequency (RF) systems, including superconducting RF cavities cooled by a 4-Kelvin liquid-helium cryogenic plant. The cryogenic plant consists of two 870-watt refrigerator/liquefier coldboxes, two 3,500L dewars, three compressors, a purifier, and associated manifold box and valve boxes, helium buffer tanks, transfer lines and a liquid Nitrogen system that supports coldbox operation. This position is responsible for the continued development, operation and optimization of the cryogenic plant, and related mechanical and utility systems. The successful candidate is expected to learn on the job all cryogenics-related concepts. You will work as a productive and collaborative member of a multidisciplinary team of engineers and technicians through all phases of sub-system design, component selection, prototyping, fabrication, installation, commissioning, operation, and troubleshooting.

Essential Duties and Responsibilities:

• Develop, commission, operate, troubleshoot and repair of cryogenic system and sub-systems, including limited off-hours support.
• Perform analysis, simulation and calculation of cryogenic and mechanical components and systems using tools such as ANSYS, Gaspak, REFPROP, CST and related codes.
• Assist in the cryogenic operation of superconducting cavities.
• Design, procure, and/or develop cryogenic subsystems to meet evolving accelerator requirements.
• Generate and maintain schematics, process flow diagrams, work instructions and technical documentation.
• Develop maintenance schedules and work plans for operating cryogenic systems.
• Maintain current knowledge of principles, methods, and best practices within the related fields.
• Mentor junior engineering and technical staff.
