Overview The Argonne Wakefield Accelerator (AWA) Group in the High Energy Physics Division at Argonne National Laboratory seeks a postdoctoral research associate to conduct experimental and computational research in accelerator science and technology. The focus is on developing and applying machine learning (ML) methods for accelerator operations and beam-dynamics optimization in advanced-accelerator applications. This work supports AWA’s mission to enable next-generation, energy-frontier particle accelerators. The AWA portfolio spans beam-driven wakefield acceleration, generation of bright electron beams, advanced beam-manipulation for precise electron-beam shaping, and ML for accelerator science. Responsibilities + Develop and deploy ML algorithms for autonomous operations and optimization of beam dynamics, beginning with macroscopic beam control (e.g., centroid and beam size) and advancing to techniques that enhance high-power, high-frequency radiation generation via wakefield production—a key element of the two-beam acceleration concept + Emphasize Bayesian optimization approaches and integrate these methods into the facility control system + Design, execute, and analyze accelerator experiments; lead experimental campaigns and contribute to operations as needed + Shape independent research directions and collaborate to apply ML tools across AWA experiments + Document methods and results; present findings internally and at external conferences; contribute to publications Collaboration Environment + Work in close coordination with ML development teams across Argonne (including the Advanced Photon Source) and with collaborators at SLAC + Engage with a multi-lab team that includes scientists from Fermilab and Jefferson Lab Application Materials Please submit: + Research statement + Official graduate school transcript + CV (including publications and presentations) Additionally, arrange for three letters of recommendation to be sent to HEPHR@anl.gov . This position will remain open until filled. **Position Requirements** + Recent or soon-to-be-completed PhD (within the last 0-5 years) in field of physics—ideally in accelerator science or engineering—or a closely related field + Demonstrated experience or strong interest in artificial intelligence and machine learning, particularly for control applications + Proficiency in Python + Strong analytical and problem-solving skills + Ability to work independently and collaboratively with scientists, engineers, and technicians + Excellent written and verbal communication skills + Collaborative mindset; works effectively with internal and external partners in a transparent, collegial environment + Demonstrated ability to think independently and innovatively to develop creative solutions + Strong organizational skills and attention to detail + Ability to model Argonne’s core values of impact, safety, respect, integrity, and teamwork Preferred Qualifications + Background in beam dynamics and electron sources + Background with wakefield acceleration techniques and diagnostics + Experience with ML frameworks such as PyTorch or TensorFlow + Experience with the software stack used at AWA: PyEPICS, GitHub, NumPy, SciPy, Matplotlib + Strong experimental skills, curiosity, and initiative in research projects **Job Family** Postdoctoral **Job Profile** Postdoctoral Appointee **Worker Type** Long-Term (Fixed Term) **Time Type** Full time The expected hiring range for this position is $70,758.00-$117,925.00.
