Talk:Wendelstein 7-X

What happened, exactly?
For a project that was supposed to take only a few years to complete, an eight year schedule slip seems to imply that something very odd happened. This article doesn't mention what that might be. And that seems to be a major failing. Can anyone expand this? Maury Markowitz (talk) 12:40, 11 June 2014 (UTC)


 * To my knowledge, the time schedule was simply to optimistic. As far as I understood there ware just many problems, as this is a quite big project with just very many possibles for failures. E.g. the superconducting coiles needed longer for delivery and where not delivered in the expected order.

 * May have been similar to the coil shape problems that caused construction of National Compact Stellarator Experiment to be halted in 2008. Stellarators difficult to build? The construction of Wendelstein 7-X. Klinger mentions many of the problems, including redesign of structures. - Rod57 (talk) 02:02, 13 December 2015 (UTC)

Update of article
The device is finished and is currently tested. — Preceding unsigned comment added by 136.206.123.117 (talk) 16:12, 3 June 2015 (UTC)

Admittedly, this is a complex subject. And most readers never majored in Physics. I at least studied Chemistry and Physics in High School.

But I think many people would want you to explain, in a simple manner, what are the major differences between the "traditional" Tokomak Fusion Reactor and this new Stellarator fusion Reactor. I think that would be good to know.Robert DelRosso (talk) 11:06, 31 October 2015 (UTC)

Wendelstein 7-AS
Redlinks really aren't that nice, so Wendelstein 7-AS should be created, it's crucial for the understanding of the research pre-7X. Thanks! :) Cheers, Horst-schlaemma (talk) 14:56, 7 November 2015 (UTC)

Cleanup needed
Even distribution of images would be a good place to start. Should the building appear in the infobox? Viriditas (talk) 11:55, 11 December 2015 (UTC)

Crazy twists
What explains the crazy twists and turns in the coils (colored blue in the figure). How was this geometry arrived at? — Preceding unsigned comment added by 89.15.238.77 (talk) 16:51, 14 December 2015 (UTC)
 * A good question - I was just asking myself the same question. The stellarator article says:
 * The basic idea of the stellarator is to use areas of differing magnetic fields to cancel out the net forces on a particle as it travels around the confinement area. Spitzer's concept used the mechanical arrangement of the confinement area to achieve this goal, while more modern systems use a variety of mechanical shapes or magnets to the same end.
 * ...so that appears to be at least a part of the answer. GregorB (talk) 14:21, 26 December 2015 (UTC)

Missing content
I noticed the following sentence was incomplete: "Then, on February 3, 2016,, with production of the first hydrogen plasma to initiate the science program." Missing content between the two comma's? — Preceding unsigned comment added by 140.211.239.121 (talk) 20:21, 21 March 2018 (UTC)

Cooperation: few countries missing
Looks like some organizations (including few from Russia) are not listed in Colaborating Institutes section. The source: https://www.ipp.mpg.de/17004/kooperationen

Timeline needs updated
The Timeline section needs updated as the last entry states that OP2 should begin in 2019. It now being December of 2019 and seems that OP2 may not begin until at least the coming year (2020.) Just a humble suggestion to keep the page from being out of date. Thank you. --HenryTjernlund (talk) 03:19, 11 December 2019 (UTC)

Triple Product -- Dimensions/Units
degree-second/m^3 is probably not correct, should rather be Ks/m^3, shouldn't it? what is the difference "degree-second/m^3" anyway :-) ?
