And indeed, 50 years later, the most strik- ing feature of the 22nd FEC was the suc- cess of this international collaboration, which resulted in tremendous scientific and technical progress. This is clearly shown by statistics: the 22nd FEC was attended by 761 participants from 42 countries; the contributions included 116 oral presenta- tions and 507 posters. In a special evening session the conference organizers celebrat- ed the anniversary by looking back on the history of 50 years of magnetic confine- ment fusion research.
