Postdoctoral Researcher in accelerator design for the FCC-ee.

Mission

The EPFL Laboratory of Particle Accelerator Physics ( LPAP ) is seeking a Postdoctoral Researcher to join our interdisciplinary team focused on developing a robust optics configuration and beam-beam collision scheme for the Future Circular Colliders ( FCC ).

As part of the CHART -funded project “General Accelerator Design at the FCC-ee: optics, tuning knobs and collective effects studies,” the successful candidate will contribute to the development of a robust and optimized FCC-ee lattice design with an emphasis on beam-beam interactions and collective effects.

The project involves refining optics configurations, implementing new tuning knobs, and developing correction schemes to enhance luminosity, beam lifetime, and dynamic aperture—critical figures of merit for collider optimization.

Initial work will include analyzing current FCC-ee lattice options, identifying sensitivities to beam-beam forces and machine imperfections, and using this knowledge to design alternative optics configurations aimed at minimizing nonlinearities and improving beam stability under high-intensity conditions.

A key aspect of the project is the development of flexible correction schemes and tuning knobs for real-time adjustment of lattice parameters during machine operation.

These tools will allow operators to adapt to varying beam conditions, mitigate the impact of beam-beam effects, and suppress resonance phenomena.

This adaptability is essential to maintaining long-term stability and ensuring the FCC-ee’s potential for high-precision physics measurements.

Research topics may include:

The postdoctoral researcher will be encouraged to tailor their work toward one or more of these focus areas, depending on their expertise and interest.

They will also support parallel developments led by PhD students, ensuring coherence in the beam dynamics models and helping to define tolerances for overall design robustness.

This position offers a unique opportunity to contribute to the design of next-generation particle colliders through cutting-edge research in accelerator physics and simulation development.
