About this position
The EPFL Laboratory of Particle Accelerator Physics (LPAP) is recruiting a postdoctoral researcher to work on accelerator design studies for the Future Circular Collider electron-positron option (FCC-ee). The project sits within a CHART-funded effort focused on building a robust optics configuration, a realistic beam-beam collision scheme, and a more stable lattice design for a next-generation collider.
The successful researcher will contribute to developing and testing alternative FCC-ee optics setups, with particular attention to beam-beam interactions, collective effects, machine imperfections, and nonlinear dynamics. The work aims to improve key performance indicators such as luminosity, beam lifetime, dynamic aperture, and beam stability under high-intensity conditions. A major part of the project is the creation of flexible tuning knobs and correction schemes that can be used to adapt lattice parameters during operation and suppress resonance effects.
Research may include developing optics tools for performance improvements with and without beam-beam effects, exploring optics concepts compatible with high-temperature superconducting nested magnet technology, and evaluating strategies for beam polarization and top-up injection. The postdoc will also support parallel developments led by PhD students, helping maintain consistency in the beam dynamics models and contributing to the overall robustness of the FCC-ee design.
The position is embedded in an interdisciplinary, international environment at EPFL and is carried out in close collaboration with FCC-ee beam physics teams.
