Comprising over one million individual components supplied by thirty-five nations, ITER is the most ambitious engineering collaboration in human history. Our documentary investigates the sheer technical challenges of assembling the world’s largest magnetic confinement tokamak.
Managing Extreme Thermal Gradients
Within a distance of just a few meters, the reactor houses the hottest spot in the solar system (150 million °C plasma) right beside superconducting magnets cooled by liquid helium to minus 269 °C—a thermal gradient unmatched anywhere in the natural universe.
