THz linear accelerators (LINACs) offer potentially higher accelerating gradients than traditional RF structures while offering inherently better stability than other novel acceleration techniques. However, many limitations still need to be overcome to enable practical applications based on THz linacs. In particular, the ability to tune the millimetre wave and THz structures that support the particle acceleration and to efficiently couple the beam from the THz sources are key to the development of THz linacs. This is an exciting project aimed at the design and realisation of appropriate millimetre wave structures that can accelerate a particle beam with low energy spread and high beam capture whilst considering the coupling into these structures in the correct mode, manufacturing and tuning of the structure and longitudinal beam dynamics. The structures developed in this project can form injectors that could be used to inject into THz linacs, other novel accelerators or RF structures where short bunches are required, where the mm-wave or THz structures could accelerate until relativistic and the velocity is fixed at close to the speed of light.
This is also a unique opportunity to join a vibrant research team from Lancaster University and The Cockcroft Institute at Daresbury Laboratory, Warrington, UK, developing world leading concepts for novel acceleration using laser-generated THz pulse. The 3.5-year project is expected to start in October 2023. The work is mainly based on numerical computation, using full wave electromagnetic codes such as CST Particle Studio. The work will include the development of prototype structures, their test in a THz bunker and data analysis. The applicant will be expected to have a first or upper second-class degree in physics or electronic engineering or other appropriate qualification. Candidates should have a good understanding of electromagnetic theory. Computational skills are desirable but not essential.

Potential applicants are encouraged to contact Dr. Rosa Letizia (email@example.com) or Prof. Graeme Burt (firstname.lastname@example.org ) for more information.
Upon acceptance of a student, this project will be 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 the student 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.
