Suppression of electron cloud in future particle accelerators using Laser Ablation Surface Engineering


Project Description

A PhD studentship is available from October 2020 to study Laser Ablation Surface Engineering (LASE) for the suppression of electron cloud in future particle accelerators. Electrons can be released into the vacuum chambers of accelerators through a variety of mechanisms, and under certain circumstances the density of electrons can become high enough to cause significant disruption to the stored beam. This is expected to be the case, for example, in the Future Circular Collider (FCC, proposed as the successor to the LHC at CERN) unless measures are taken to suppress the build-up of electron cloud. One very promising technique is to use a laser to treat the inner surface of the vacuum chamber, changing the morphology in such a way as to limit the number of electrons emitted when photons or charged particles strike the chamber wall.

However, studies of LASE-treated surfaces have so far been done only at room temperature, whereas machines such as FCC will make extensive use of superconducting technology and will therefore have long sections of vacuum chamber maintained at cryogenic temperatures. The goal of this project is to assess the effectiveness of LASE for the suppression of electron cloud in vacuum chambers at cryogenic temperatures, and to study any potential adverse impacts from the LASE treatment on the overall performance of an accelerator. The project will involve extensive experimental work with laser, vacuum and cryogenics equipment, and with surface analysis apparatus. The studies will also involve data analysis and some computer modelling work.

The applicant will be expected to have a first or upper second class degree in physics or other appropriate qualification. Experience with laser, vacuum and cryogenics equipment is desirable but not essential, as is experience in accelerator and computational physics. A full graduate programme of training and development is provided by the Cockcroft Institute. The student will be registered for a PhD at the University of Liverpool, but will be based primarily at the Cockcroft Institute at Daresbury where most of the work will be carried out.
Potential applicants are encouraged to contact Prof. Andy Wolski () or Dr. Oleg Malyshev () for more information. This position will remain open until filled.
