摘要 在 HL-2A 托卡马克装置上开展了逆剪切阿尔文本征模 (RSAE) 引起的热离子传热实验研究。研究发现,RSAE在锯齿波周期的后半段受到通过粒子的驱动而变得不稳定,不仅会降低轫致辐射,而且会导致核心等离子体中离子温度的明显降低。有趣的是,高能离子激发的RSAE可以与热离子共振,然后导致热传输过程。统计结果表明,热离子热通量扰动与模式振幅之间存在二次相关性,这表明等离子体输运的扩散机制,并且可以通过准线性输运理论得出的理论解释得到很好的解释。
Abstract Experimental investigations of thermal ions heat transport induced by reversed shear Alfvén eigenmodes (RSAEs) have been carried out on the HL-2A tokamak. It is found that the RSAEs are driven unstable by passing particles during the second half of sawtooth periods, and can not only degrade the bremsstrahlung radiations, but also cause obvious reduction of the ion temperature in the core plasma. Interestingly, the RSAEs excited by energetic ions can resonant with the thermal ions, and then lead to a heat transport process. Statistical results suggest there is a quadratic dependence between thermal ion heat flux perturbation and mode amplitude, which indicates a diffusive mechanism of plasma transport and is well explained by the theoretical interpretations derived from quasi-linear transport theory.
