Radiation cooling with intrinsic and injected impurities in the plasma boundary of a limiter tokamak
The study of plasmas with various levels of radiation is a subject of ongoing research on TEXTOR. In particular, emphasis has been placed on investigating the properties of plasmas with a cold radiative edge close to the density limit (detached plasma). Initially, these studies concentrated on the case of pure ohmic heating, but recently have been extended to discharges with strong auxiliary heating. A quasi-stationary high radiation level has been achieved by injecting Ne into the plasma. In the present paper these results are summarised. The radiation characteristics are discussed, and the data are compared with the requirements for radiation cooling in a fusion plasma.
