[School of Natural Sciences PhD Scholarships] Next-Generation Compact Accelerators and Radiation Sources Based on Intense Laser–Plasma Interactions

About the project

About the Project Research into intense laser–plasma interactions for compact particle accelerators and advanced radiation sources has attracted considerable interest over the past few decades, driven in particular by the development of high-intensity laser technologies such as chirped-pulse amplification (CPA). Plasma-based accelerators can sustain accelerating electric fields that are orders of magnitude higher than those achievable in conventional radio-frequency (RF) accelerator structures, offering the potential to dramatically reduce the size, cost, and infrastructure requirements of future accelerators. Intense laser–plasma interactions provide a route to compact accelerators and table-top X-ray and gamma-ray sources with unique properties. This PhD research encompasses both gaseous plasmas and emerging solid-state and nanostructured plasma concepts, including carbon-nanotube-based systems. These advanced accelerator concepts have potential applications across fundamental physics, industry, medicine, and national security. The radiation sources provide ultrashort pulse durations reaching the femtosecond or attosecond regime, high peak brightness, and potentially high photon flux. Such sources could enable new applications in ultrafast imaging, medical imaging, photonuclear physics, high-energy-density science, and strong-field quantum electrodynamics (QED). The availability of state-of-the-art multi-hundred-terawatt (TW) and petawatt (PW)-class laser facilities, including the Extreme Light Infrastructure (ELI) facilities in Europe and high-power laser facilities in the UK, creates exciting opportunities to explore these regimes experimentally. This is a 3–3.5-year PhD position starting in October 2027. The project will investigate novel schemes for compact particle acceleration and high-energy X-ray/gamma-ray generation. The research will combine theoretical and computational approaches, including classical electrodynamics, plasma physics, accelerator physics, particle-in-cell (PIC) simulations, high-performance computing (HPC), and advanced machine-learning methods. The student will be registered at the University of Manchester and will work closely with collaborators across the Cockcroft Institute and its partner universities and ELI collaborators. An important component of the project will be the development of concepts and simulations that can contribute directly to future experimental proposals for X-ray and gamma-ray generation at multi-hundred-TW and multi-PW laser facilities in the UK and Europe. The project therefore offers an opportunity to work at the intersection of plasma physics, accelerator physics, high-power lasers, computational physics, machine learning, and advanced radiation sources, with a strong connection to future experimental programmes.
