The first large production order for the Wendelstein 7-X fusion experiment, construction of the plasma chamber, has been successfully completed: The 20 sectors of the bizarrely shaped 35-ton vessel were assembled from several hundred individual components – an engineering masterpiece. Installation of the whole complex device, which started in spring 2005 at the Greifswald branch of Max Planck Institute of Plasma Physics, will take about six years.
