Postdoctoral Researcher - Machine Learning for Accelerator Science (Argonne Wakefield Accelerator)

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@ . 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
