Modelling of JET DT experiments in ILW configurations

Numerical scan at constant β shows that core and scrape‐off layer (SOL) radiations do not depend on the plasma current ( I p ). Whereas the SOL radiation increases with seeding, the core radiation, however, does not continue to increase with seeding but rolls over at higher seeding rates in the simulations. The core plasma contamination by W ions is low, c W ≪ 10 −4 . When the seeding starts, an increase in radiation power leading to a …
