Cryogenic Engineer

Brookhaven National LaboratoryUpton, NY
Onsite

About The Position

The National Synchrotron Light Source (NSLS-II) is a state-of-the-art electron storage ring producing extremely bright x-rays for research across various scientific disciplines. The NSLS-II RF Group is responsible for designing, fabricating, operating, and maintaining high power Radio Frequency (RF) systems, which include superconducting RF cavities cooled by a 4-Kelvin liquid-helium cryogenic plant. This cryogenic plant comprises refrigerator/liquefier coldboxes, dewars, compressors, a purifier, associated manifold and valve boxes, helium buffer tanks, transfer lines, and a liquid nitrogen system. This position focuses on the continued development, operation, and optimization of this cryogenic plant and related mechanical and utility systems. The successful candidate will learn cryogenics-related concepts on the job and work collaboratively within a multidisciplinary team of engineers and technicians throughout all phases of sub-system design, component selection, prototyping, fabrication, installation, commissioning, operation, and troubleshooting.

Requirements

  • B.S. in Mechanical Engineering, Chemical Engineering, Cryogenic Engineering or Physics with a minimum of seven (7) years of relevant experience, including at least five (5) years of combined experience in development and operation of cryogenic systems or similarly complex mechanical systems with a demonstrated record of successful contributions.
  • Demonstrated experience with structural or thermal simulation tools such as ANSYS, CST, Refprop, Gaspak, Aspen HYSYS, or equivalent multiphysics analysis software.
  • Experience of using common components, tools and equipment, such as pressure gauges, temperature sensors, cryogen level sensors, flow meters, pressure relief valves, control valves and pressure relief valves.
  • Excellent written and verbal communication skills.
  • Strong interpersonal skills with the ability to work effectively in a diverse technical team environment.
  • Availability for limited off-hour on-call support for urgent operational issues (typically < 2%).

Nice To Haves

  • B.S. in Mechanical Engineering, Chemical Engineering, Cryogenic Engineering or Physics with a minimum of ten (10) years of relevant experience.

  • Experience with cryogenic systems and components for superconducting cavities or magnets for accelerator applications.
  • Experience in pressure and cryogenic safety analysis.
  • Experience with process controls and feedback loops.

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.
