20 ERO code

ERO is a code that solves the kinetic equations of impurities in tokamak plasma in the vicinity of material surfaces such limiters (the parts of a fusion device nearest the plasma) or divertors (a device within a tokamak that allows the online removal of waste material from the plasma while the reactor is still operating). In the EUROfusion device JET, the code is already used to investigate carbon-13 marker injection experiments, migration of eroded wall material to remote areas, erosion of poloidal limiters, quantification of beryllium sputtering yields on poloidal limiters, and migration of beryllium from the plasma facing wall onto the tungsten divertor. The use of this ERO code can spread to beyond fusion into areas that involve plasma-wall interactions, such as plasma gasification of waste, electrostatic and electromagnetic space propulsion systems, and effects of space plasmas on spacecraft.

The complexity and the multidisciplinary nature of fusion research produced number of spin-offs that have found applications in industry, other scientific disciplines, and technological advances. The areas that have benefited from fusion research span a variety of fields ranging from medicine and material science to computing and astrophysics.

EUROfusion has identified some of these spin-offs, looked at fusion research aspects that have the potential for short-term benefits, and prepared a non-exhaustive list of fusion spin-offs which demonstrate the short-term benefits of fusion research on the way to fusion electricity.
