The dynamic behaviour of the electron temperature profile was studied in different phases of the TEXTOR Tokamak discharge. The Te profile evolution was observed during start-up, flat-top and current ramp-down phase. Detailed measurements during sawtooth activity and density limit disruption were obtained. The heat diffusivity chi e was evaluated from heat pulse propagation data. The energy and current quench times were recorded in a density limit disruption after a preceding Te profile contraction.
TEXTORトカマク放電の異なる位相における電子温度分布の動的挙動を研究した。立ち上げ時、平坦部、電流減衰位相におけるTe分布の時間発展を観測した。鋸歯状振動活動中および密度限界崩壊時の詳細な測定を行った。熱パルス伝播データから熱拡散係数χeを評価した。先行するTe分布の収縮後の密度限界崩壊において、エネルギー消失時間と電流消失時間を記録した。
