Terahertz-Integrated Structures for Novel Accelerators

About the project

About the Project Develop next-generation particle accelerators powered by laser-driven terahertz (THz) radiation. Join leading researchers at Manchester and the Cockcroft Institute to design integrated THz structures achieving extreme acceleration gradients and femtosecond beam control—advancing ultrafast physics and compact accelerator technology. This PhD will pioneer compact, high-gradient particle accelerators powered by laser-driven terahertz (THz) radiation—electromagnetic waves a thousand times faster than those used in conventional accelerators. Working with experts at the University of Manchester and the Cockcroft Institute, you will design and build integrated THz-waveguide structures capable of achieving gigavolt-per-metre acceleration. The project combines experimental laser physics, ultrafast optics and simulation to push the limits of accelerator technology and open new opportunities in materials science, imaging and particle physics. PhD in Terahertz-Integrated Structures for Novel Accelerators University of Manchester and Cockcroft Institute | Start date: October 2026 | 3.5 years | Fully funded (UK eligibility rules apply) Particle accelerators drive discovery in physics, chemistry, and medicine—but conventional radio-frequency (RF) accelerators are limited to accelerating fields around 100 MV/m before electrical breakdown occurs. This restricts how compact and powerful they can be. To overcome this, this PhD will develop a new generation of compact, high-gradient accelerators powered by laser-driven terahertz (THz) radiation—electromagnetic waves oscillating a thousand times faster than microwaves. The THz acceleration group at the Cockcroft have already demonstrated dielectric-lined THz waveguides that synchronise THz pulses with relativistic electron bunches, enabling acceleration far beyond RF limits. The next step is to increase the field strength inside these structures by improving THz generation, coupling, and mode conversion. The aim is to build an integrated THz device that generates and shapes the accelerating field within a single structure, eliminating energy losses and opening new frontiers for THz-based acceleration, compression, and beam diagnostics. During the first year, the student will receive training in experimental laser physics, THz generation, and numerical modelling, gaining hands-on experience with the Cockcroft’s high-power laser facilities. The second year will focus on designing and fabricating integrated THz-waveguide structures and testing them. Later in the project, these devices will be applied in large-scale accelerator experiments at the CLARA facility (Daresbury Laboratory) and international laser centres such as ELI-ALPS. The student will join the Cockcroft Institute , a UK centre of excellence in accelerator science that connects the THz acceleration group members from the Universities of Manchester and Lancaster with STFC’s Daresbury Laboratory. This environment provides advanced training, access to world-class laboratories, and opportunities to collaborate across physics, engineering, and materials science. This PhD is ideal for students with a strong background in physics, electrical engineering, or related disciplines, and an interest in laser systems, electromagnetism, or accelerator science. Experience in optics or simulation tools is desirable but not essential.
