Nevertheless, it should demonstrate that stellarators are also suitable as a power plant. After a break for New Year, confinement studies will continue in January, which will prepare the way for producing the first plasma from hydrogen. Pipes were joined using a special welding technique developed at the ITZ. She was inaguriating the fusion reactor Wendelstein 7-X, the world’s largest stellarator, by generating its first hydrogen plasma. With full cooling, longer pulses with plasma energies of up to one gigajoule should be possible. We’re not changing over to the actual investigation object, a hydrogen plasma, until later this year,” explains project leader Professor Thomas Klinger: “This is because it’s easier to achieve the plasma state with helium. 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 addition, we can clean the surface of the plasma vessel with helium plasmas.”. środa, Listopad 28, 2018 - 12:40 komentarzy: Stellarator Wendelstein 7-X bije kolejne rekordy wydajności plazmy.

Some rooms also offer a balcony. Wendelstein 7‐X soll die Kraftwerkstauglichkeit dieses alternativen Konzepts demonstrieren. Orders in excess of 70 million euros were placed with companies in the region. Wendelstein is a 1,838-metre-high (6,030 ft) mountain in the Bavarian Alps in South Germany. Earlier this year, the Wendelstein 7-X stellarator fusion project reported record achievements from its most recent experimental campaign. The Wendelstein 7-X - the world's largest stellarator-type fusion device - started scientific operation yesterday with the production of its first hydrogen plasma, the actual investigation object. Following the conclusion of main assembly in 2014 at the Max Planck Institute for Plasma Physics (IPP) in Greifswald, Germany, the machine achieved its first helium plasma in December 2015 and its first hydrogen plasma in February 2016 . Both types of system are being investigated at the IPP. Numerous research facilities at home and abroad were involved in the construction of the device. During the course of the step-by-step upgrading of Wendelstein 7-X, the plasma vessel was fitted with inner cladding beginning in September of last year. The main assembly of Wendelstein 7-X was completed at IPP in Greifswald in 2014, and first plasma was produced in December 2015.

It will test an optimised magnetic field for confining the plasma, which will be produced by a system of 50 non-planar and superconducting magnet coils, this being the technical core piece of the device. Its purpose is to advance stellarator technology: though this experimental reactor will not produce electricity, it is used to evaluate the main components of a future fusion power plant; it was developed based on the predecessor Wendelstein 7-AS experimental reactor. 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 planned to begin with low water cooling, low heating power and short plasma pulses. This will enable a discharge length of 30 min.
