First detachment studies on COMPASS tokamak using nitrogen seeding.
Original language description
Partial detachment is considered to be a mandatory regime for ITER and next-step devices, as it allows to dissipate a substantial part of the heat flux carried by the plasma particles and significantly reduce the heat fluxes deposited on the divertor target tiles. Despite that, most studies of power deposition in contemporary tokamaks were performed in attached plasmas[1].nDetached regimes tend to be more difficult to access and diagnose - for example the infrared thermography (the principal diagnostics for such studies) suffers from interference caused by increased bremsstrahlung in the infrared spectrum in detached plasmas. COMPASS has a combination of a relatively short connection length to the target and an open divertor geometry, which was considered unfavourable for detachment access. In order to facilitate access to partially detached regime of operation, impurity seeding in the divertor region can be employed. In this paper, we report on first results from the impurity seedingnexperiments, which were performed in Ohmic plasmas.
