本文介绍了 HL-2A 托卡马克装置的最新实验结果。使用带有液氮高温推进剂的超音速分子束注射（SBI）。低温SMBI可以形成氢簇，更深入、更有效地渗透到等离子体中。使用调制 SMBI 在等离子体外围获得粒子扩散系数和对流速度（分别为 D = 0.5–1.5 m2 s−1 和 Vconv < 40 m s−1）。多探头测量首次同时观察到直接测量的低频（7-9kHz）电势和场的 m = 0–1、n = 0 对称性。杂质输送由激光吹气系统和输送代码决定。根据 MHD 活动观察和统计分析得出了中断预测因子。研究了 ECRH 期间的锯齿特性，并研究了 m = 1 和 m/n = 2/1 模式之间的耦合。使用SOLPS5.0程序和实测数据对HL-2A偏滤器的脱离特征进行了数值和实验研究。 HL-2A 中较长的偏滤器腿和较薄的偏滤器喉部会造成 MHD 成形问题，导致即使在低密度下也会造成动量损失，并大大增强主室损失。
Recent experiment results from the HL-2A tokamak are presented in this paper. Supersonic molecular beam injection (SMBI) with liquid nitrogen temperature propellant is used. Low temperature SMBI can form hydrogen clusters that penetrate into the plasma more deeply and efficiently. Particle diffusion coefficient and convection velocity (D = 0.5–1.5 m2 s−1 and Vconv < 40 m s−1, respectively) are obtained at the plasma periphery using modulated SMBI. Multi-probe measurements reveal the m = 0–1, n = 0 symmetries of directly measured low frequency (7–9 kHz) electric potential and field are simultaneously observed for the first time. Impurity transport is determined with the laser blow-off system and transport code. A disruption predictor has been derived based on MHD activity observations and statistical analysis. Sawtooth characteristics during ECRH are investigated and coupling between m = 1 and m/n = 2/1 modes is studied. Detachment features of HL-2A divertor are numerically and experimentally studied using the code SOLPS5.0 and measured data. The long divertor legs and thin divertor throats in HL-2A pose MHD shaping problems resulting in momentum losses even at low densities and strongly enhanced main chamber losses.
