Abstract
In this study, the gas-fueling rate in radiatively improved (RI) mode plasmas on the limiter tokamak TEXTOR-94 was optimized in order to maintain a sufficiently low neutral pressure in the scrape off layer (SOL). As a result, it was possible to substantially overcome the Greenwald limit under quasistationary conditions with confinement of ELM-free H-mode quality, high β, q = 3.4, and a regime favorable for heat and particle exhaust.
