Lower hybrid accessibility in a large, hot reversed field pinch

R.A. Dziubek, R.W. Harvey, S.A. Hokin, E. Uchimoto1996年被引用 4Nuclear FusionIF 3出版社

Accessibility and damping of the slow wave in a reversed field pinch (RFP) plasma is investigated theoretically, using projected Reversed Field Experiment (RFX) plasma parameters. By numerically solving the hot plasma dispersion relation, regions of propagation are found and the possibility of mode conversion is analysed. If the parallel index of refraction of the wave is chosen judiciously at the edge of the plasma, the slow wave is accessible to a target region located just inside the reversal surface without mode conversion. Landau damping is also optimized in this region. A representative fast electron population is then added in order to determine its effect on accessibility and damping. The presence of these electrons, whose parameters were estimated by extrapolation of Madison Symmetric Torus (MST) data, does not affect the accessibility of the wave. However, the initial phase velocity of the wave needs to be increased somewhat in order to maintain optimal damping in the target zone

反场箍缩(RFP)等离子体中慢波的可达性与阻尼在理论上进行了研究,采用了投影反场实验(RFX)等离子体参数。通过数值求解热等离子体色散关系,找到了传播区域,并分析了模式转换的可能性。如果在等离子体边缘恰当地选择波的平行折射率,则慢波可以在不发生模式转换的情况下到达恰好位于反场面内侧的目标区域。朗道阻尼也在该区域得到优化。随后加入了一群代表性的快电子,以确定其对可达性和阻尼的影响。这些电子的参数是通过对麦迪逊对称环(MST)数据的 extrapolation 估算得到的,它们的存在并不影响波的可达性。然而,为了在目标区域维持最佳阻尼,波的初始相速度需要适当增大。
