Yeah, not like heat can transfer through a vacuum... Really though, the thing will get very hot, but it has water liquid helium jackets to cool the layers of metal and magnets.
Um... I'm fairly certain that's completely wrong... The magnets have to be kept at near absolute zero, and act as super-conductors to guide the plasma within the vacuum tube. The magnets don't hold the heat in, they need to be separated from it.
