Discover your future at Berkeley Lab!

Berkeley Lab (LBNL) addresses the world’s most urgent scientific challenges by advancing sustainable energy, protecting human health, creating new materials, and revealing the origin and fate of the universe using interdisciplinary teams and by creating advanced new tools for scientific discovery. Founded in 1931, Berkeley Lab’s scientific expertise has been recognized with 13 Nobel prizes. The University of California manages Berkeley Lab for the U.S. Department of Energy’s Office of Science.

Berkeley Lab’s Advanced Light Source (ALS) is seeking an Accelerator Floor Operator. The incumbent will provide safety oversight of the experimental floor and act as a liaison for technical and operations support on the experimental floor. This individual will assist experimenters and beamline scientists in the safe operation of the accelerator facility experimental floor.  This position will set up, operate and maintain control of accelerator and beamline equipment and support systems. The Operator will provide a preliminary diagnosis of any trouble encountered with accelerator and beamline equipment, and will support experimenter needs and comply with standards and practices to ensure safe accelerator facility operating conditions.

The ALS is a dynamic national scientific user facility that provides thousands of scientists from around the world access to bright beams of x-rays, infrared, and extreme ultraviolet light for scientific studies and technology development in disciplines spanning physical, chemical, materials, biological, energy, and Earth sciences. The ALS has been a global leader in soft x-ray science for more than two decades and is currently undertaking a new project (ALS-U) that will endow the facility with state-of-the-art x-ray capabilities. It’s an exciting time to join our growing team!

The core values of the Advanced Light Source (ALS) reflect a strong commitment to diversity, equity, and inclusion. The ALS offers an environment that celebrates diversity and embraces inclusion. We seek candidates that would support a culture where all of the ALS’s staff and scientists—regardless of race, ethnicity, sexual orientation, gender identity, age, language, abilities/disabilities, socioeconomic status, geographic region, or other defining characteristics—should feel welcome and valued.

  • Key-enables and takes beamlines offline, as required.
  • Ensure that the appropriate procedures are followed, with special attention to any changes that might require control of radiation shielding.
  • Make clear logbook entries of work done on beamlines and end stations.
  • Ensure radiation safety via radiation monitoring during routine operations, commissioning activities, and during troubleshooting scenarios.
  • Monitor components of the ALS beamline vacuum system.
  • Recognize changes to experimental equipment that might introduce new hazards, triggering reviews as necessary.
  • Aids in the use of the Equipment Protection Systems and the Radiation Safety Systems to ensure safe, efficient use of beam time.
  • Diagnose ALS experimenters’ needs and coordinate technical support from ALS and LBNL crafts and trades, including electronic and mechanical repair, survey and alignment, conventional facilities, etc.
  • Provide experimenters with assistance and training in the safe use of ALS user labs, the experimental area, user staging areas, and user shops and other workshops during off hours.
  • Provides Emergency Response and mobilize response teams as necessary.

What is Required:

  • Coursework in basic engineering and/or scientific principles and related subject matter comparable to the technical content of a four-year post-secondary school curriculum, or an equivalent combination of education and experience.
  • Ability to monitor accelerator and accelerator beamline performance.
  • Capability of understanding complex systems and identifying standard hardware failures.
  • Familiarity with physics theory, as it forms the basis for the performance of the accelerator system.
  • Effective communication skills for interacting with operations support staff and experimenters.
  • Written communication skills sufficient to provide accurate and concise documentation of operations activities.
  • Must be able to work on weekends and in rotating shift schedules, as required.
  • Experience collaborating in a diverse multidisciplinary team environment with excellent interpersonal skills.
  • Ability to interact with a variety of technical and scientific personnel with varied academic backgrounds.
