Finnfusion Annual Seminar 2024

Welcome to the Finnfusion Annual Seminar 2024!

The seminar will take place on May 27-28th, 2024 in Helsinki. Organized jointly by the University of Helsinki and VTT, the 2-day seminar will include presentations, poster session, dinner and an Accelerator Laboratory tour. Participation is free of charge. For more details and addresses, please see the agenda.

Registration ended on May 3rd, 2024. For late registration, please contact Fredric Granberg (fredric.granberg@helsinki.fi).

The first day of the seminar is in the UH's City center campus, and the second day will be in Kumpula campus. Reaching Kumpula from the city center is easy (there are several direct bus lines, approx. 15 minutes). For those living outside Helsinki, Pasila train station is approx. 2km from Kumpula campus and can be reached on foot (25 min) or by bus (line 506). If your train passes through Pasila, consider taking the train from there.
