ALS Lead Radiation Physicist – 87912
Organization: AL-Advanced Light Source

Berkeley Lab’s Advanced Light Source (ALS, is seeking a Lead Radiation Physicist. The primary role and responsibilities of this position involve shielding design, radiological calculations and considerations, beamline and accelerator review, and operational procedures. This work will be performed for the exiting ALS Facility and for the planned upgrades to the accelerators and beamlines (ALS-U Project).

This position will be hired at a level 4 or 5 contingent upon level of experience, skills, knowledge, and abilities of the successful candidate.

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. We seek candidates who will support a culture in which the entire ALS community feels welcomed and valued.

What You Will Do:
• Execute calculations related to radiation shielding for both upgrades to existing equipment and for the design of new components for the new facility.
• Ensure Accelerator Safety Order compliance by assisting with beamline design and participating in configuration control.
• Work in collaboration with accelerator physicists, calculating heat loads on collimators, optical components, shutters and beam-stops.
• Maintain and develop Monte Carlo and analytic radiation transport computer tools for radiological studies.
• Participate in research and development activities in health/radiation physics in support of the ALS & Lawrence Berkeley National Lab (LBNL) mission and publish results.
• Supervise the development of synchrotron and Bremsstrahlung ray trace drawings for new/altered beamlines and accelerators
• Participate in the Integrated Safety Management (ISM) analysis of experiments conducted by ALS staff and Users.
• Participate in ALS Review Committees (Accelerator Review Committee, Beamline Review Committee, Technical Review Committee, ALARA Subcommittee, ALS Radiation Review Committee).
• Oversee accelerator operations by monitoring and interpreting data from radiation monitors, dosimetry, and beamline and accelerator surveys.
• Analyze and designate monitoring locations for alterations in beamlines or accelerator components.
• Analyze, consider and propose a course of action in response to changes in Department of Energy (DOE) orders, LBNL procedures, or the ALS safety environment.

Additional Responsibilities as needed:
• Participate in Lab-wide committees and working groups as appropriate to your skills and Lab needs.

What is Required:
• PhD in Physics, Health Physics, Nuclear Engineering or related fields or equivalent work experience; 3-5 years working in an accelerator environment, including demonstrated experience with shielding design, activation calculations, and radiation safety systems.
• Demonstrated experience dealing with Monte Carlo radiation generation and transport codes (FLUKA, MARS15, MCNP, PHITS, etc.).
• Experience dealing with technical, operational, scientific and administrative staff and Users, preferably at a national laboratory.
• Experience with the theory and operation of radiation monitoring equipment.
• Experience working with scientific staff, technical staff, and with people from diverse geographic backgrounds.
• Advanced verbal and written communication skills to clearly and effectively communicate with divisional leaders, managers, staff, and other stakeholders.
• Demonstrated skills to develop organization-level and other high-impact communications and presentations.
• Adhere to the Lab’s “Stop Work” Authority at

Additional Qualifications for Lead Radiation Protection Specialist position:
• PhD in Physics, Health Physics, Nuclear Engineering or related fields or equivalent work experience; a minimum of 7 years working in an accelerator environment, including demonstrated experience with shielding design, activation calculations, and radiation safety systems.

Additional Desired Qualifications:
• Familiarity with DOE Accelerator Safety Order and Guidance documents.
• Experience in interacting with peers in the DOE complex and other light sources.

The posting shall remain open until the position is filled, however for full consideration, please apply by close of business on 8/26/2019.

• This is a full-time career appointment,exempt (monthly paid) from overtime pay.
• Classification will depend upon the applicant’s level of skills, knowledge, and abilities.
• This position may be subject to a background check. Any convictions will be evaluated to determine if they directly relate to the responsibilities and requirements of the position. Having a conviction history will not automatically disqualify an applicant from being considered for employment.
• Work will be primarily performed at Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA.
