Fusion grad student here. HL-2M is very similar to the US DIII-D reactor in size, magnetic field strength, and plasma current. HL-2M will have 11 MW of heating power in its first stage compared to 23 MW on DIII-D according to Wikipedia, tho

If you have Alfred, you can sort of do this with an extension I made: https://github.com/sballin/alfred-search-notes-app The default search looks for folder names too, so searching "[folder name]" will bring

I'm a PhD student studying turbulence at the outer edge of plasmas in fusion experiments. Turbulence degrades plasma confinement, which makes it difficult to keep the plasma burning and produce power. I'm interested in whether dif

The fast ion loss probe used in fusion energy research is relevant to your last point. See figure 1 of [1], or if you have access see [2] for a good explanation. [1] https://w3.pppl.gov/~szweben/Papers/coauthorpape

I'm not the expert on this, but I was curious so I looked into it a bit. I don't believe it required significant resources or crazy algorithms, but a clever selection of physics criteria to optimize. It was a ~20-dimensional Neuma

I guess the word pinhole is misleading here, I think it's a few cm in diameter. Behind it there's an array of lenses that projects the view onto a fiber bundle, then a lens at the other end of the bundle projects that view out. Th

I operate a fast camera at W7-X. It's a normal high-speed camera that records light in the humanly visible range, and the plasma emits in that range and reflects off the walls. IR cameras are most often used to gauge the temperatures o

Here's a source, unfortunately paywalled, from 1989: https://www.tandfonline.com/doi/abs/10.13182/FST90-A29178 I do research at W7-X, so I can confirm that to the best of my knowledge, the design was com
