Master Thesis Placement in system‑identification of the SLS2 storage‑ring RF and analysis of the electron‑beam response to RF‑modulation
We at the Paul Scherrer Institute (PSI) are offering a master thesis placement focused on the system‑identification of the SLS2 storage‑ring RF system and the analysis of the electron‑beam response to RF‑modulation. The project is structured into core tasks and an optional advanced task for experienced students.
Your tasks
* Core tasks:
o Model the RF system, measure its characteristics at the teststand and at the storage‑ring with the stored electron beam, and improve the model and parameters.
o Include RF‑modulation, the harmonic cavity, and the second‑order momentum compaction factor into the Hamiltonian of synchrotron motion; analyze the evolution of the RF bucket and try to reduce transient beam‑loading effects.
* Advanced task (for experienced students): Evaluate the potential of RF‑modulation to reduce the energy‑spread (minima of the oscillation) in synchrotrons.
Your profile
* Foundational knowledge of calculus, linear algebra, and complex numbers.
* Proficiency in writing simple scripts in Python or Matlab.
* Interest in RF systems for synchrotrons.
* General interest in particle accelerators.
Other information
PSI is the largest research institute for natural and engineering sciences in Switzerland. The master’s thesis does not involve employment at PSI. Duration is around 6 months, preferably starting in early 2026. For further information please contact Dr Lukas Stingelin (phone +41 56 310 58 41). Please submit your application online for the master thesis project (index no. 8413‑25852).
