About the Project

The UK is on a path to building an X-Ray Free Electron Laser (X-FEL). High brightness ultra-fast X-Ray pulses from an X-FEL allow the simultaneous imaging of atomic scale structure, electronic state and dynamics in a material. There is no other technology that can do that. The unique science opportunities include, observing dynamical phenomena on a time scale down to femtoseconds thus covering electronic dynamics, lattice dynamics and chemical bonds breaking/forming.

Free Electron Lasers use a relativistic electron beam as a gain medium for generating electromagnetic radiation. The radiation is generated when the electron beam passes through a periodic magnetic structure, known as an undulator. The frequency and power of operation can be changed by adjusting properties of the electron beam.

The electron beam of the UK X-FEL will be accelerated by RF-Cavities. These cavities resonate with high power microwaves which are generated by klystrons. The main objective of this work is to design cutting-edge RF circuits to control high power klystrons to ensure amplitude and phase stability of less than 1 degree, critical to the operation of the X-FEL.

The candidate should have a strong understanding of electromagnetism. Experience with high-frequency circuitry and RF-Engineering, is desirable. The successful candidate will be expected to provide some teaching assistance a few weeks each year. 

Deadline for applications: 31st August 2022

Start Date: October 2022.

The successful candidate will conduct the work and study at Daresbury Laboratory (near Warrington).

Funding Notes

A full PhD studentship is offered by the Engineering Department at Lancaster University. The funding covers the cost of tuition fees and a standard tax-free RCUK stipend (£ 16,062 per annum for 22/23 academic year) for 3.5 years for UK applicants. Non-UK students are welcome to apply, but overseas tuition fees will be charged.
