Job Description

The Argonne Wakefield Accelerator (AWA) Group, part of the High Energy Physics (HEP) Division at Argonne National Laboratory, seeks a postdoctoral research associate 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 machine learning and beam manipulation to develop new beam physics capabilities and improved accelerator beamline operations

(2) assist with the development of AWA’s beam-driven Wakefield acceleration schemes

(3) help to maintain AWA’s cathode test stand for collaborative research

Position Requirements
