In the vacuum created inside the shell, the coils are cooled down to superconduction temperature close to absolute zero using liquid helium. Earlier this year, the Wendelstein 7-X stellarator fusion project reported record achievements from its most recent experimental campaign. Wendelstein 7-X, the world's largest stellarator-type fusion device, will not produce energy. Preparatory work was extensive. The current leads, which must make the transition from superconducting tem-perature to room temperature, have been successfully designed, tested, and are now being manufactured. It is part of the Mangfall Mountains, the eastern part of the Bavarian Pre-Alps, and is the highest peak in the Wendelstein massif.It lies between the valleys of the Leitzach and Inn and is accessible via the Wendelstein Cable Car and the Wendelstein Rack Railway. In Garching, the Tokamak ASDEX Upgrade is in operation and, as of today, the Wendelstein 7-X stellarator is operating in Greifswald. “Most of the old components had to be taken out.

The coolant is supplied by small steel tubes to ensure that the heat energy is removed. At present, only a tokamak is thought to be capable of producing an energy-supplying plasma and this is the international test reactor ITER, which is currently being constructed in Cadarache in the frame of a worldwide collaboration. It is planned to begin with low water cooling, low heating power and short plasma pulses. Although Wendelstein 7-X is not designed to generate energy, the device is intended to prove that stellarators are suitable for use in power stations.

Wendelstein 7-X at the Greifswald branch of IPP is a large stellarator with modular superconducting coils which enable steady state plasma operation in order to explore the reactor relevance of this concept. As the fusion fire only ignites at temperatures of more than 100 million degrees, the fuel – a thin hydrogen plasma – must not come into contact with cold vessel walls. Dubbed Wendelstein 7-X (W7-X), the reactor in Greifswald, Germany is hoped to continuously contain super-hot plasma for more than 30 minutes at a time. For Reporters. For the magnetic cage, two different designs have prevailed – the tokamak and the stellarator. “Wendelstein 7-X has just started operation, with the aim to show that the earlier weaknesses of this concept have been addressed successfully, and that the intrinsic advantages of the concept persist,” the researchers explained in the study. It should show that stellarators - with discharges lasting 30 minutes - have the ability to operate continuously. Each technical system was tested in turn, the vacuum in the vessels, the cooling system, the superconducting coils and the magnetic field they produce, the control system, as well as the heating devices and measuring instruments.
