Much of the remaining physics and engineering challenges for fusion centre on handling the issues of heat exhaust and developing robust solutions for the wall, blanket and magnets of the device. Fusion reactors create huge amounts of energy that must ultimately be intercepted by the walls. Heat and particles create extreme challenges for materials in contact with the plasma, while the fusion reaction also creates copious neutrons that on the one hand damage and activate materials, but also carry the energy that will be extracted and used. This course will cover the knowledge and skills required to understand the ‘outer half’ of the magnetic confinement fusion reactor, from the scrape-off-layer and sheath through the first wall, tritium breeding blanket and superconducting magnets.
