ABSTRACT:
Two dimensional (2-D) images of electron temperature fluctuations with high temporal and spatial resolution have been employed to study the sawtooth oscillation (m/n=1/1 mode) in Toroidal EXperiment for Technology Oriented Research (TEXTOR) tokamak plasmas. 2-D imaging data revealed new 토토 사이트 순위 which were not available in previous studies based on the 1-D electron temperature measurement and X-ray tomography. The new insights are: A pressure driven instability (not a ballooning mode) leads to theX-point reconnection process. The reconnection process is identified as a random 3-D local reconnection process with a helical structure. The reconnection time scale is similar for different types of sawtooth oscillation (kink andtearing type) and is significantly faster than the resistive time scale. Heat flow from the core to the outside of the inversion radius during the reconnection process is highly collective rather than stochastic. Review of the 토토 사이트 순위 of the sawtooth oscillation is given by comparative studies with prominent theoretical models suggest that a new 토토 사이트 순위 paradigm is needed to describe the reconnection 토토 사이트 순위 of the sawtooth oscillation.
