The electron cyclotron resonance heating (ECRH) experiments on HL-1 tokamak with 300kW of power generated by a gyrotron are described. With ECE diagnostics, a 30% increase of electron temperature has been obtained. The following phenomena have been observed with various diagnostics during ECRH: increase of radiation intensity of soft X-ray;amplitude change and period elongation of sawtooth oscillation; MHD instability suppression; increase of Hα spectral fine intensity and ionized impurity radiation from edge plasma;increase of the temperature and density of edge plasma. Although the total plasma energy content increases, the energy confinement time is decreased. Initial results of low voltage start-up experiments have also been obtained. 相似文献

聚变等离子体的光谱诊断,国内外已有了许多工作。如何在短波长上获得等离子体丰富的光谱信号,从而确定高温等离子体参数,是目前一个有意义的工作。 本工作在一台θ箍缩装置上,用掠入射真空紫外光谱仪,以对联三苯闪烁体为荧光转换材料,观测了类氦的CV40.2/40.7A,OⅦ21.6/21.8A等谱线信号,及CⅥ33.7A,OⅧ19.0 相似文献
