How can particle accelerators address environmental issues?

A 10-day challenge for multidisciplinary teams of young people!

The 2023 I.FAST CBI will take place from Tuesday July 25th to Thursday August 3rd 2023. The application form is here.

We invite you to take part in an EU-funded challenge to imagine new multidisciplinary solutions to address environmental issues by using particle accelerators. This challenge will be tackled by multidisciplinary teams invited to stay, all expenses covered (*), for 10 days at the European Scientific Institute (ESI – on the France-Geneva border.

The application form is here.

Some particle accelerators such as the Large Hadron Collider (LHC) at CERN are the largest scientific tools on Earth. But beyond driving large scientific discoveries, many smaller accelerators are used in medicine to cure cancer and they also have many other applications in our daily lives.

During 10 days, you will join a team of 6 students and young people with different academic backgrounds (communication, law, environmental sciences, physics and engineering) to imagine innovative solutions on “how can particle accelerators be used to tackle environmental challenges?”. On the 10th day, you will present your work to a jury of experts at CERN.

To help in this task, you will be offered high-level seminars on particle accelerators, on environmental challenges and on innovation as well as a stimulating environment to discuss these issues.

This initiative is put forward by the I.FAST project, funded by the European Union’s Horizon 2020 research and innovation programme. It stems from the historic collaboration between the ESI, CERN and others partners to run the Joint Universities Accelerator School.

Who can apply?

Applications are welcome from all applicants.

  • Preference will be given to students in the second cycle of university studies (typically between the 3rd and 5th year of university).
  • We expect to select students in the following academic fields: communication, law, environmental sciences, physics and engineering.
  • Priority will be given to those studying in universities located in countries members of I.FAST (see list at ).


All activities will be held in English.
