Abstract

As the operation of future devices will require target heat fluxes of less than 10-20 MW/m2, finding ways of dissipating the power before it reaches the divertor targets is a critical issue. This can be achieved by injecting low-Z impurities in the divertor to radiate part of the power. Impurity seeding can also facilitate the access to a detached regime where a reduction of target heat loads and a drop of the target ion flux is associated with the development of momentum losses along the SOL. Such a regime is expected to be necessary in ITER or DEMO, and in both experiments, it is expected that impurity seeding will be required to access it.
