Armin Ilg: The experimental challenge at the Future Circular Collider

Tuesday 19 May 2026, 13:15 → 14:00 Europe/Stockholm

FB54 (AlbaNova Main Building)

The Future Circular Collider (FCC) is a proposed next-generation particle accelerator with a circumference of 90.7 km, intended to succeed the Large Hadron Collider (LHC) as the world’s leading collider facility. In its first stage, FCC-ee will operate as a high-luminosity electron–positron collider, delivering unprecedented precision across a centre-of-mass energy range from 88 to 365 GeV.

This seminar will present an overview of the FCC programme and its accelerator design, followed by a discussion of the experimental challenges at FCC-ee. Particular emphasis will be placed on how the ambitious physics goals drive the requirements on detector performance. The interplay between these benchmarks and the design of the detector subsystems will be highlighted, along with an overview of the key technologies being developed to meet these challenges.

About the speaker: Armin Ilg is an experimental particle physicist working on state‑of‑the‑art tracking detectors, as well as simulation and reconstruction algorithms for next‑generation particle colliders experiments. He completed his MSc and PhD at the University of Bern (Switzerland) on the ATLAS ITk upgrade, including a search for supersymmetry in mixed‑flavour final states, before shifting his focus to vertex detector concepts for the FCC‑ee. His work has demonstrated the potential of Monolithic Active Pixel Sensors (MAPS) for ultra‑light vertex detectors through detailed full‑simulation studies. He is currently an SNSF Ambizione Fellow at the University of Zürich (Switzerland) pursuing this research direction.
