Managing the extreme heat in a tokamak fusion device - introducing the divertor

The divertor is the exhaust system of the tokamak, the world's most advanced fusion device. It gives us a way of managing the high levels of heat and power from the hot plasma fuel, and also a way of removing impurities. Here, Dr Melanie Windridge is joined by Dr Steven McNamara, Physics Programme Manager, and Dr Daniel Iglesias Ibanez, Divertor Team Leader, to show us how divertors, limiters and sacrificial regions can be used to manage the extreme heat loads in the tokamak.
