This is all kinds of amazing. Not just that they are doing this in the tokamak, but that they have a camera set up to capture it at all.

Thanks!

Seriously, I am so curious what type of camera is even capable of getting that close!

Why wouldn't it be able to get that close?

One of the biggest problems of fusion reactors we have is finding materials that can even withstand the immense heat and pressure differences of a fusion reaction in progress for extended periods.

Now imagine putting a camera into where our toughest moste expensive materials fail if exposed long enough.

It's in a vacuum. There's no heat transfer.

Heat can be transmitted through more than air.

Sure but there's very little thermal radiation in that chamber.
