The following footage was captured inside the Compass Tokamak at Institute of Plasma Physics IPP last year.
It's pretty beautiful, and it shows exactly what happens inside these huge devices.
It was the first high-speed color footage, fimed at up to 20,000 flames per second, from inside a fusion reactor.
The entire process only takes around 2 seconds in real time.
It shows the formation of a plasma column as deuterium gas is heated by an electric current and trapped by a magnetic field.
The flashing lights are dust particles interacting with the plasma.
And this is footage of the JET (Joint European Torus) Fusion reactor.
Here is a video about how it all works. I love this channel :)
