The breadth and coverage of analytical expertise in the IEA Technology Collaboration Programmes (TCPs) are unique assets that underpin IEA efforts to support innovation for energy security, economic growth and environmental protection. The 38 TCPs operating today involve about 6 000 experts from government, industry and research organisations in more than 50 countries1.

Wendelstein 7-X virtual tour

Take a virtual tour through the Wendelstein 7-X (W7-X), the world's largest fusion device of the stellarator type. This 360-degree panorama takes you into the experimentation hall, the plasma vessel, and the beam duct. View short videos, call up background information, and zoom in on minute details. The W7-X is co-ordinated through the TCP on Stellarator-Heliotron Concepts (SH TCP).   

Constructing the Wendelstein 7-X fusion device 

A three-minute time lapse video shows the stages of construction of the Wendelstein 7-X (W7-X) fusion device from 2005 through to 2014. The world's largest fusion stellarator device, the W7-X is co-ordinated through the SH TCP.     

Wendelstein 7-X project wins "Landmark" prize

The project, "Wendelstein 7-X: for the Power Plant of Tomorrow", is one of the prizewinners in the 2016 "Landmarks in the Land of Ideas". The competition is intended to promote outward looking ideas that use the potentials of community in the form of joint action, co-operation and networking, and thus enhance joint efforts to meet present and future challenges. More...

First plasma achieves around one million degrees for 1/10th of a second

Following nine years of construction work and more than one million assembly hours, the main assembly of the Wendelstein 7-X was completed in April 2014, and 10 December 2015 saw helium plasma achieved for 1/10th of a second operating at a temperature of around one million degrees. Watch this short video which captures the atmosphere during the operational start of the W7-X. Wendeslstein 7-X is one of the devices co-ordinated through the TCP on Stellarator-Heliotron Concepts (SH TCP).  More...
