What are all the valves and ports and things in the metal outside of the stellarator in the lead illustration?

  Heating and diagnostics. https://www.researchgate.net/figure/Port-allocation-of-the-W7-X-heating-systems-showing-the-positions-and-injection-geometry_fig10_271978056 https://www.researchgate.net/figure/Port-allocation-of-the-W... There's a chapter on W7-X diagnostics in this DOI (check sci-hub). It doesn't include a comprehensive list of diagnostics or their port assignments, but it was the best I found at a glance. 10.1007/978-1-4613-0369-5_76

    At first I thought they lacked symmetry. Now I see they don’t, it’s just pretty convoluted

      W7-X has 5 periods and each period is a mirrored half period, so really it's one segment repeated 10 times. This pattern is common to symmetric stellarators.

  You need to start these things with a hard vacuum inside before you inject your fusile material.
