The first milestone in the successive assembly of the Wendelstein 7-X fusion device at the Greifswald branch of Max Planck Institute of Plasma Physics (IPP), Germany, has been reached on schedule with the completion of the first two half-modules of the large-scale experiment: Two-tenths of the inner core of the device is now ready and is being assembled. Industrial production of the essential components for Wendelstein 7-X is almost complete. Construction of the complex device will take about another six years.
