Basic Purpose

The Argonne Wakefield Accelerator (AWA) Group, part of the High Energy Physics (HEP) Division at Argonne National Laboratory, seeks an Assistant Physicist to conduct experimental, computational, and theoretical research in accelerator science & technologies. The AWA’s mission is to carry out the R&D needed to develop the next generation of accelerators.  Its research portfolio includes the development of beam-driven wakefield acceleration, the generation of bright electron beams, and the deployment of novel beam-manipulation techniques for precise electron-beam shaping.  The AWA facility incorporates several RF photocathode electron beamlines (a 70 MeV linear accelerator complemented with a beam-shaper, a 15 MeV linear accelerator and a 3 MeV cathode test stand) and a large experimental switchyard dedicated to research in advanced accelerator R&D.  The AWA facility pioneered the development of beam-driven structure-wakefield acceleration (SWFA).

Position Description:

The AWA Group performs hands-on, cutting-edge research along multiple accelerator R&D thrusts including advanced acceleration concepts, machine learning for accelerators, beam physics and accelerator technologies, high-gradient RF structures, novel diagnostics and novel cathode developments.  Over the next five years, the AWA plans to expand its program in machine learning applications to beam control and virtual diagnostics and to demonstrate critical SWFA experiments (e.g. a collinear wakefield energy doubler and a 500-MeV two-beam accelerator) in support of future linear colliders, soft X-ray light sources and compact accelerators. We are a hands-on group that performs a mix of in-house staff-driven research and a closely related collaborator-driven research program. The successful candidate will (1) majorly participate in AWA’s ongoing accelerator research programs in beam-driven wakefield acceleration methods and novel accelerating structure development; (2) help to grow AWA’s machine learning program and coordinate with AWA’s beam physics program to explore beam-structure interaction; and (3) help to maintain AWA’s cathode test stand for collaborative research.

Required experience:

  • RF structure design using 3D simulation codes such as CST Microwave Studio to model beam-wave interaction.
  • RF structure fabrication participation with designers and machining
  • Low-level RF benchtop measurements of structures using VNA and similar instruments.
  • Experimental high-power tests of RF structures. 

Desired experience:

  • Familiarity structure wakefield acceleration, plasma wakefield acceleration, collinear wakefield acceleration and two beam acceleration.
  • Familiarity with electron beamlines and the ability to operate an accelerator. 

General requirements:

  • Ph.D. in Physics or Engineering with a focus on the particle accelerators.
  • Enjoys working in teams, including the ability to interact well with external collaborators, while operating in a transparent & friendly work environment.
  • Thinks and works independently and innovatively to develop creative solutions.
  • Respects, understands, and values individual differences.
  • Abides by all environment, safety, and health regulations.
  • Good verbal and written communication skills, and the ability to write research reports and publications.  
  • Organizational skills and attention to detail. 

The selected candidate will be placed at the appropriate level dependent upon depth and breadth of relevant knowledge and skills brought to the position, as well as the amount of relevant experience. The requirements of the various levels are as follows:

  • RD2 (assistant physicist) Level: Above and 3+ years as postdoc
  • RD3 (physicist) Level: Above and 5+ years’ experience as an assistant physicist 

The following documents are required to apply for this position. - Research Statement - Official Graduate School Transcript - CV (including publications & presentations). In addition, please arrange to have three letters of recommendation sent to:  For full consideration please submit all materials by May 14th, 2021.  This position will remain open until it is filled.
