Job ID 3321 Date posted 07/25/2022

Brookhaven National Laboratory ( delivers discovery science and transformative technology to power and secure the nation’s future. Brookhaven Lab is a multidisciplinary laboratory with seven Nobel Prize-winning discoveries, 37 R&D 100 Awards, and more than 70 years of pioneering research. The Lab is primarily supported by the U.S. Department of Energy’s (DOE) Office of Science. Brookhaven Science Associates (BSA) operates and manages the Laboratory for DOE. BSA is a partnership between Battelle and The Research Foundation for the State University of New York on behalf of Stony Brook University. BSA salutes our veterans and active military members with careers that leverage the skills and unique experience they gained while serving our country. Our organization fully supports service members transitioning from active duty to civilian life and pledge’s our commitment to actively hire veterans of the U.S. Armed Forces. Military personnel who have been formally trained or have relevant experience obtained while in service may meet educational requirements and are encouraged to apply for job opportunities at BSA.

Organizational Overview
The mission of the Collider-Accelerator Department (C-AD) is to operate, maintain, improve, and upgrade the suite of electron, proton, and heavy ion accelerators used to carry out a program of accelerator-based experiments at Brookhaven National Laboratory (BNL). To support this program, the C-AD must design, fabricate, assemble, test, install, and operate unique research equipment to generate, transport, transfer, accelerate, focus, track, collide, and absorb high intensity particle beams up to energies of 250 GeV.  This includes a combination of custom designed and built parts and vendor produced components developed by a collaboration of the C-AD scientific, engineering, and technical staff. The C-AD supports an international user community of over 1,500 scientists. The C-AD performs all these functions in an environmentally-responsible and safe manner, under a rigorous conduct of operations approach.

Position Description

Within the C-AD, the Accelerator Division has an opening for an experienced Engineering Manager and/or Cryogenic or Mechanical or Electrical Engineer to lead the C-AD Cryogenics Group.  The C-AD Cryogenics Group is responsible for the operations, maintenance, and upgrade of the Relativistic Heavy Ion Collider (RHIC), Central Liquid Helium Refrigerator Plant (LHe plant) and distribution system.  This system cools over 1000 RHIC superconducting magnets and superconducting RF (SRF) cavities.  The RHIC LHe plant will be upgraded to increase the cold end capacity and improve efficiency in preparation for the Electron Ion Collider (EIC) operations.  The C-AD cryogenics group is partnering with the Thomas Jefferson National Laboratory to design, fabricate, and install new satellite plants and distribution systems that are needed for additional SC magnets and SRF cavities required for EIC.   In addition, the C-AD Cryogenics Group operates a small LHe plant for the C-AD SRF cavity test facility.  This facility is being upgraded to improve its capability and throughput including the procurement and installation of a larger 1kW4.5K LHe plant and LHe distribution system.  The C-AD Cryogenics Group also supports other cryogenics systems throughout the BNL complex and participates in DOE level cryogenic reviews.  This effort is being supported by a C-AD Cryogenics Group staff which includes 10 engineers consisting of plant process, mechanical, electrical, controls engineers, and system controls programmers.  The group also includes 20 mechanical and electrical technicians or system operations, maintenance, repairs, and upgrades under supervision by a mechanical group technical supervisor and an electrical group technical supervisor. This position has a high level of interaction with an international and multicultural scientific community.

Essential Duties and Responsibilities:

  • Lead, coordinate, and supervise the operations of existing RHIC cryogenic systems and the development of system upgrades and new systems needed for RHIC and EIC.  This will be from initial concept through engineering analysis, detailed design, procurement, documentation and fabrication drawings, assembly, testing, installation, and commissioning. 
  • Working with the C-AD Cryogenic Group engineering supervisors and system and project leads in the engineering staff, manage and oversee individual engineering projects and the development of project plans including defining and documenting scope, labor and material resources, schedules, procurement plans, and subsequent tracking and reporting on these projects through to completion.
  • Manage, supervise, and guide the C-AD Cryogenics Group staff. 
  • Maintain and develop the staff and infrastructure with high standards for quality of work and ensure that qualified staff are assigned to carry out the technical tasks.
