概要
- 論文の詳細を見る
Impurity pellets of stainless steel and plastic carbon with a size of 0.5mm^φ and a velocity of 400±100m/s have been injected into fast-wave-current-driven plasmas with a sustained plasma current of 35-50kA and an electron density of 2-4×10^<12>cm^<-3> to study the interaction between them. The current-driven plasmas show no disruption at the pellet injection, whereas all of the ohmic discharges are disruptive. These phenomena are interpreted briefly with results of a sudden decrease of the electron temperature and density rises of 6-8×10^<12>cm^<-3> for the iron pellet and 4×10^<12>cm^<-3> for the carbon pellet. The electron temperature after the injection is estimated to be about 10eV from the density rise and the calculation of the impurity charge states. The decaying time of the injected impurity is measured to be 25ms from the time behaviour of the soft x-ray emission.
