Premiere day: As not all ITER staff could attend the Prince's address, a live feed was installed and over 200 people saw the live broadcast on "ITER's internal portal "buzz".

Female fusion scientist are rare and the more attractive for the media: Sophie Carpentier giving an interview to Monaco TV.

The Prince had a last quick chat with the Fellows before he boarded his helicopter taking him back to Monaco.

And last but not least it was Fellow Sophie Carpentier to explain to the Prince what challenges lie ahead in the quest for fusion energy.

Evgeny Veshchev introducing the difficult task of tracking alpha particles in a plasma.

Fellow Axel Winter was the second to give a summary of his research.
