Job Description

We have an opening for a Postdoctoral Researcher to play a leading role in developing a light-ion accelerator for the Livermore Nuclear Science (LiNuS) Center. Your responsibilities will include design and modeling of a high-current light-ion accelerator, participating in the fabrication and testing of accelerator structures, analyzing the resulting data, and interpreting and publishing the results. You will be responsible for the design and start-to-end simulation of the LiNuS accelerator system including incorporation into the existing radiation shielding infrastructure. This position is in the Nuclear Physics and Accelerator Technologies Group of the Nuclear and Chemical Sciences Division.

In this role you will 

  • Perform beam dynamics simulations of the accelerator system including the source, beam transport sections, accelerator sections, compression system, and distribution to experimental end stations
  • Perform radio frequency and magnetic modeling of accelerator structures, deflector cavities, and transport magnets
  • Oversee the fabrication, low-power, and high-power testing of novel ion accelerator structures
  • Functioning as part of a team, collaborate with scientists, engineers and technicians in the assembly, commissioning, operations, and maintenance work on RF accelerator systems currently being operated in Building 194
  • Publish research results in peer-reviewed scientific or technical journals and present results at external conferences, seminars, and/or technical meetings
  • Work in close collaboration with colleagues at SLAC National Accelerator Laboratory to model, fabricate, and test accelerator structures
  • Provide technical contributions to new proposals for accelerator-driven science at LLNL, specifically utilizing the Neutron Imaging, Mega-Ray Test Station, and PRISM accelerators operated in Building 194
  • Perform other duties as assigned


  • PhD in Accelerator Physics, Electrical Engineering, or related field
  • Demonstrated experience with beam dynamics simulation tools such as PARMELA, GPT, particle-in-cell codes, or similar programs
  • Demonstrated experience with electromagnetic simulation tools such as HFSS, Microwave Studio, Poisson/Superfish, or similar programs
  • Experience in fabrication and operation of normal or superconducting RF accelerators
  • Broad experience in accelerator hardware systems such as high vacuum systems, high voltage equipment, beam diagnostics, complex mechanical design and assembly, control systems, cooling systems, and beamline alignment
  • Documented publication record in peer-reviewed literature in physics or a related field
  • Experience working collaboratively as part of a focused team
  • Excellent verbal and written communication skills to collaborate effectively in a multi-disciplinary team environment and present and explain technical information
