@ElmarMoelzer Von der Konfiguration ist aber Helion schon FRC, ist natürlich richtig, dass diese dann stark komprimiert werden sollen, was wieder eher zu zap passt. Ist kein eindeutiger Fall, da passt diese vereinfachende Tabelle nicht

Hier der Versuch, die Fusionsfirmen/-startups, die es so gibt, zu sortieren.

@Stefan_Urbat nt-tao ist etwas schwierig, die sagen ja, sie verwenden ihre eigene, geheime Plasmaheizung. Die Teilchendichten sollen allerdings 3 Größenordnungen über denen bei MCF liegen, daher eher bei "weitere"

[Alf Köhn-Seemann @formbar]

@Gregdt1 It certainly is an interesting field, I agree! Let me know if you're interested in a second PhD 😉

[Alf Köhn-Seemann @formbar]

PhD-student wanted: the project is about plasma-technological processes that use electrical energy from renewables to provide base chemicals for the chemical synthesis industry or to produce synthetic fuels. Mostly numerical, with a few experiments. Awaiting your applications!

@Stefan_Urbat JT-60SA hasn't seen a plasma yet, so it is not yet a "real" tokamak (soon hopefully will be)

[Alf Köhn-Seemann @formbar]

On my way to Culham (well, just arrived, obviously), home of both, the world largest tokamak and the world largest spherical tokamak.

@mancan Will explore the pub there tonight 👍

[Alf Köhn-Seemann @formbar]

@gmeni Good point about indicating a few configurational aspects in the plot, will play around a little

[Alf Köhn-Seemann @formbar]

If stellarators are your thing, you might be interested to hear that ~60 stellarators have been operated or are currently in operation around the world. You might also like this plot, showing their magnetic field strength and major radius (symbol size indicative of minor radius)

[Alf Köhn-Seemann @formbar]

@renfusion Indeed, that would require a re-scaling, overshadowing a lot of the other experiments ;-)

[Alf Köhn-Seemann @formbar]

@gmeni Was also thinking about other ways to put all those Stellarators into one plot, e.g. taking into account heating power (varies during operation time), l or m values (not too informative), triple product (not that easy to get all the data and in principle already existing)

[Alf Köhn-Seemann @formbar]

Interested in what typical master theses projects with fusion relevant topics typically look like? This meeting at the @Uni_Stuttgart might be for you: master students from around Europe will defend their theses, in-person, open to anyone.

@ElmarMoelzer Thanks anyway! I guess I found something, although it's not that clear, but one is a classical Stellarator, the other a torsatron - at least according to some few references I was able to find

[Alf Köhn-Seemann @formbar]

I'm wondering if any of my fusion friends here knows the difference between the L-2 and the L-2M stellarator...?
I would be interested to know!

Poster session at the #eps2023 : warm (rather hot to be honest), noisy, exhausting, but at the same time great because all these are probably just due to the intense discussions going on at the posters. Really enjoying it!

[Alf Köhn-Seemann @formbar]

First in person EPS conference on Plasma Physics in Bordeaux about to start, already excited and looking forward to meet colleagues and friends from around the world I haven't seen in 4 years!
#eps2023

[Alf Köhn-Seemann @formbar]

@TokCOMPASS Haha, indeed 😅

[Alf Köhn-Seemann @formbar]

When the conference organizer publishes the schedule 3 weeks before the conference, you see that your presentation is scheduled for Friday afternoon and of course you have already booked the return trip, leaving the conference site on Friday at lunch time.

[Alf Köhn-Seemann @formbar]

@JosefineProll @JB_Fusion Haha, good point!
