  Fully-funded PhD in Sustainable High Power RF Amplifiers for Muon Colliders


   School of Engineering

   Applications accepted all year round  Funded PhD Project (UK Students Only)

About the Project

A student is sought for a PhD study on the development of high efficiency RF amplifiers for the Muon Collider design study at CERN. Current particle accelerators use huge amounts of energy but not all of it goes into the beam, a significant fraction is lost as heat due to the inefficiency of the RF amplifiers, known as klystrons. This additional energy must be delivered from the electrical grid and hence leads to higher CO2 emissions. Future colliders will need to be more sustainable and a collaborative program at CERN and Lancaster University has been developed to develop higher efficiency klystrons to meet future needs of a number of future projects. One such project is the muon collider which is a large particle accelerator that will collide muons to study high-energy physics at scales beyond the LHC. Lancaster University is leading the development of the klystron for the muon collider design study.

The PhD student will use state-of-the-art simulation codes and high power computing to study the different technology options for the muon collider RF amplifier, working in synergy with the development of klystrons for other projects at CERN and the Cockcroft Institute, and will investigate how the achievable efficiency and power scales with different frequency choices. Novel methods of further increasing efficiency will be innovated looking at the full amplifier system including power supplies, magnetic focusing, electron sources, and the spent beam collector. This project is a unique opportunity to be at the forefront of the move to more sustainable and socially responsible solutions to big science.

The applicant will be expected to have a first or upper second class degree in physics, electronics or nuclear engineering and should have a good understanding of electromagnetism. The student will also be joining the Cockcroft Institute and will take part in a world leading PhD training program on particle accelerators.

Funding Notes

Upon acceptance of a student, this project will be funded (including both stipend and fees) for 3 years; UK 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.
