kρυός (kryo) very cold
It will be very hot in ITER. And it will be very cold also — "down to temperatures," says Luigi Serio in this video, "that do not naturally occur on Earth."
Why do we need extreme cold in ITER? To allow magnets to reach a state of superconductivity and to "clean" the vacuum in the cryostat by having particles stick to the cold surfaces ... like when your finger sticks to the ice compartment in your refrigerator, "but more complicated," says Luigi.
