Optics measurements and corrections for future electron colliders and light sources
Electron storage rings have been instruments of choice for precision measurements both in High Energy Physics colliding beam experiments, as well as experiments with synchrotron radiation in materials science, life science, and others. The new generation of storage rings aims to push the limits of the luminosity and the size of the electron beam that can be achieved. Two of such planned machines are the e+/e- Future Circular Collider (FCC-ee) and PETRA IV. The FCC-ee is a proposed 100km circumference collider for precision studies and rare decay observations in the range of 90 to 350 GeV centre of mass energy with luminosities in the order of 10^35 cm^−2 s^−1 (https://home.cern/science/accelerators/future-circular-collider). PETRA IV is a planned 6 GeV synchrotron light source at DESY, Hamburg which is expected to replace the existing PETRA III facility and commence operation at DESY in 2027. Once operational, PETRA IV will be the brightest hard x-ray synchrotron source worldwide (http://www.desy.de/research/facilities__projects/petra_iv/index_eng.html).
This project would allow the PhD student the opportunity to work at world class facilities (DESY, Cockcroft Institute and CERN), and to work on research crucial for both particle colliders and synchrotron light sources.
A common challenge of such low emittance storage rings is their high sensitivity to errors and the need for precise control of beam parameters such as the emittance. Novel algorithms for orbit correction, linear optics correction, beam-based optimization of nonlinear dynamics and emittance tuning will be important to reliably run these facilities. Such algorithms rely upon multi-parametric optimisation problems with multiple unknowns under dynamically changing conditions such as changing ambient temperatures, and power supply instabilities.
This project aims at developing novel algorithms for optics tuning which explore the possibility of predictive models to speed-up procedures, performing simulations for FCC-ee and PETRA IV followed by experimental verification at PETRA III.
The successful applicant will spend the majority of their time based in Hamburg, Germany, with opportunities to travel to CERN. They will be registered at the University of Liverpool.
