Funded PhD Project (European/UK Students Only)
Laser-driven acceleration in dielectric structures is capable of GV/m acceleration gradients and control of sub-femtosecond beams. The field is undergoing a resurgent interest internationally, with large programmes such as the ‘accelerator on a chip’ programme and ERC programmes in THz-driven acceleration in optimised Dielectric Laser Acceleration (DLA) structures completing in 2018, having delivered a strong track record of publications.
In this project you will extend DLA modelling and optimisation to high scientific impact experimental demonstrations, working in collaboration between Liverpool, PSI and KIT, Lancaster and ASTeC. The project will develop structures for experimental demonstration of acceleration and deflection at both the Paul Scherer Institute and CLARA at Daresbury. You will undertake modelling of structures identified through previous work, with scaling to longer wavelength narrow-band sources that offer increased acceptance for acceleration. In anticipation of the experimental programme, the electron beam modelling will incorporate known (experimentally determined) beam parameters from Swiss-FEL and CLARA. In collaboration with PSI you will participate in the design and manufacture of structures optimised for experiments at Swiss-FEL and CLARA. You will also have a central role in delivering experiments involving PSI collaborators and CI partners.
For the CLARA experiments you will have responsibility for the experimental system integration of manufactured structures, laser sources, and the electron-beam optics design and optimisation.

The project is fully funded by the Science and Technology Facilities Council for 3.5 years; UK and other EU citizens are eligible to apply. A full package of training and support will be provided by the Cockcroft Institute, and you will take part in a vibrant accelerator research and education community of over 150 people. An IELTS score of at least 6.5 is required.
