Sakemannit ovat viilanneet varsin vaatimatonta, mutta selkeästi potentiaalia omaavaa, Wendelstein 7-X laitettaan ja fuusiplasman koossa pysymisen uusi ennätys ko laitteella on nyt 43 sekuntia. Omakehu haisee ja sakemannit väittää löytäneensä oikeat aeetukset sun muut ja kohta on odotettavissa puolentunnin pläjäys. Jäämme odottamaan.

The Wendelstein 7-X reactor, however, is a stellarator—it uses a related, albeit more complicated, design that doesn’t induce an electric current in the plasma but instead tries to control it with powerful external magnets alone. The result is that the plasmas in stellarators are more stable within their magnetic bottles. Reactors like the Wendelstein 7-X aim to operate for a longer period of time than tokamaks can without damaging the reactor chamber.

The Wendelstein researchers plan to soon exceed a minute and eventually to run the reactor continuously for more than half an hour. “There’s really nothing in the way to make it longer,” explains physicist Thomas Klinger, who leads the project at the Max Planck Institute for Plasma Physics. “And then we are in an area where nobody has ever been before.”

Ja fransmannit on jätetty uutisoimasta täällä, ranskalaiset pamautti ennätyksen plasman kestossa WEST laitteessaan helmikuussa; 22 minuuttia. Ja ranskalaiset väittää saavansa tuntien keston seuraavaksi, jäämme odottamaan.

1,337 seconds: that was how long WEST, a tokamak run from the CEA Cadarache site in southern France and one of the EUROfusion consortium medium size Tokamak facilities, was able to maintain a plasma for on 12 February. This was a 25% improvement on the previous record time achieved with EAST, in China, a few weeks previously.

This is what CEA researchers intend to achieve and what explains the current record. Over the coming months, the WEST team will double down on its efforts to achieve very long plasma durations – up to several hours combined – but also to heat the plasma to even higher temperatures with a view to approaching the conditions expected in fusion plasmas.

WEST is a CEA facility that benefits from the commission’s decades of experience in the use of tokamaks to study plasmas. It welcomes researchers from around the world, who make use of its key characteristics that allow long-duration plasmas, particularly its superconducting coils and actively cooled components. WEST is one facet of an international movement comprising other major experiments in which CEA researchers are heavily involved, such as JET, the Joint European Torus tokamak in the United Kingdom (closed in late 2023), which holds the record for fusion energy, JT-60SA in Japan, EAST in China, and KSTAR in South Korea, not to mention the flagship machine that is ITER.

Kehitystä lämmönhallinnassa. Saadaanko tämä jossain muodossa ITERiin jää kysymykseksi?

10x cut in fusion reactor heat could be achieved with Super-X exhaust’s long ‘legs’
This new design provides more space for the super-hot plasma to cool down before it reaches any solid surface.

Interesting Engineering, China's Experimental Advanced Superconducting Tokamak, or EAST, set a new world record in terms of duration of a certain type of operation at or above a key threshold temperature.

As the news outlet reported, EAST became the first fusion reactor to achieve "steady-state, long-pulse H-mode plasma operations" at a temperature above 100 million degrees Celsius (180 million degrees Fahrenheit) for 17 minutes and 46 seconds, setting a new benchmark for the technology.

Fuusio on Saatanasta eikä tule toimimaan energian tuotannossa. Nyt kun soditaan niin tuollainen yksi kompleksi on liian helppo kohde viholliselle ja sabotööreille.
