Abstract
Experiments on strong radiative layers have been undertaken in Tore su pra. They have been performed in ohmic and auxiliary heated (by means of ion cyclotron resonant waves) plasmas. The high radiation level has been triggered by either deuterium or gaseous (generally neon) impuri ty injection. The ergodic divertor activation has provided an enhanced radiated fraction compared to the limiter case. Radiated power could be as high as 5.5 MW, corresponding to about 80% of the total injected for a bulk neon concentration lower than 1%.
