The last coil of the Wendelstein W7X stellarator left CEA-Saclay last week, on Wednesday 9 September 2009 to be precise. The event marks the end of trials on the 70 coils of this fusion reactor and seals the success of a major project that began in 1998 and involved many teams from IRFU (formerly known as DAPNIA).
