A detector for the next CERN flagship project: ILD

14 Sept 2026, 13:00 → 16 Sept 2026, 15:30 Europe/Zurich

The ILD concept group will organise a 3 day meeting at CERN from September 14 to 16, to discuss the state of ILD, and the way forward. A key goal of the meeting will be to understand and advance the state of the integratino of ILD into FCCee. 

At this meeting, ILD will also formally transition to the new management. 

The meeting is going to be organised as a hybrid event - while in-person attendance at CERN is much appreciated, sessions will be transmitted on zoom. When registering, please indicate whether you intend to participate in person or remotely. 

If you need CERN guest status to enter the campus, please follow the link "CERN registration" and fill our the form, in addition to the regular registration to the event.
