Physicist Postdoctoral Fellow (BELLA) - 83111
Organization: AF-Accelerator Tech-Applied Phys

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. 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.

Position Summary:
The Physicist Postdoctoral Fellows at the BELLA Program of the Accelerator Technology and Applied Physics Division ( will perform experimental research in the area of guiding intense laser beams using special fibers and study the interaction of ultra-short laser pulses guided by such fibers with gaseous and/or plasma targets for generation of low energy (MeV) electrons. The research is carried out in a team of scientists, postdocs and students with mechanical and electronics support.  

Specific Responsibilities:
• Design, build and test/debug experimental apparatus to guide laser pulses in special fibers.
• Carry out experiments on characterizing the laser pulses and on maximizing the energy transmission through the fiber and the peak power emerging from the fiber.
• Design, build and test experimental apparatus to generate electron beams at the MeV energy level and minimize the amount of energy needed through the use of optimized gas and plasma targets.
• Use laser diagnostics, image processing and control systems based on LabVIEW and Matlab and write and use programs for data processing and analysis.
• Assist in the operation of ultra-fast (< 40 fs), terawatt laser system and associated ultra-fast diagnostics such as single shot autocorrelators, frequency resolved optical gating system, optical spectrometers, etc.
• Work closely in a team with other scientists, postdocs, graduate students and technicians.
• Document and communicate the results of work in reports and oral presentations, including participation in meetings, reviews, conferences and publications in refereed journals.
• Conduct original research independently.
• Adhere to Environment, Safety, and Health (EH&S) policies and practices.

Required qualifications:
• Recent Ph.D. in Physics or engineering or a related field.
• Experience in laser guiding in optical fibers, including hollow core fibers.
• Significant experience with short pulse lasers at the terawatt level or beyond, including diagnosing, stretching and compressing pulses.
• Experience with LabVIEW.
• Ability to work independently and in collaboration with scientists both within and outside LBNL.
• Excellent analytical, organizational and multitasking skills.
• Good communication skills.
• Ability to present research results effectively.
• Availability to travel and present work at collaboration meetings, workshops and conferences.

Additional desired qualifications:
• Experience with laser plasma acceleration.
• Experience with detection of electron beams and characterizing their properties (energy, spatial profile, divergence, bunch duration).

The posting shall remain open until the position is filled.


• This is a full time 1 year postdoctoral appointment with the possibility of renewal based upon satisfactory job performance, continuing availability of funds and ongoing operational needs. You must have less than 3 years paid postdoctoral experience. Salary for Postdoctoral positions depends on years of experience post-degree.
• Full-time, M-F, exempt (monthly paid) from overtime pay.
• This position is represented by a union for collective bargaining purposes.
• Salary will be predetermined based on postdoctoral step rates.
• Work will be primarily performed at Lawrence Berkeley National Lab, 1 Cyclotron Road, Berkeley, CA.
