The physics experiments on the HL-2A tokamak have been focused on confinement improvement, particle and thermal transport, zonal flow and turbulence, filament characteristics, energetic particle induced modes and plasma fuelling efficiency since 2008. ELMy H-mode discharges are achieved in a lower density regime using a combination of NBI heating with ECRH. The power threshold is found to increase with a decrease in density, almost independent of the launching order of the ECRH and NBI heating power. The pedestal density profiles in the H-mode discharges are measured. The particle outward convection is observed during the pump-out transient phase with ECRH. The negative density perturbation (pump-out) is observed to propagate much faster than the positive one caused by out-gassing. The core electron thermal transport reduction triggered by far off-axis ECRH switch-off is investigated. The coexistence of low frequency zonal flow (LFZF) and geodesic acoustic mode (GAM) is observed. The dependence of the intensities of LFZFs and GAMs on the safety factor and ECRH power is identified. The 3D spatial structures of plasma filaments are measured in the boundary plasma and large-scale structures along a magnetic field line analysed for the first time. The beta-induced Alfvén eigenmodes (BAEs), excited by large magnetic islands (m-BAE) and by energetic electrons (e-BAE), are observed. The results for the study of fuelling efficiency and penetration characteristics of supersonic molecular beam injection (SMBI) are described.

HL-2Aトカマクにおける物理実験は、2008年以来、閉じ込め改善、粒子および熱輸送、帯状流と乱流、フィラメント特性、高エネルギー粒子誘起モード、およびプラズマ燃料供給効率に焦点を当ててきた。ELMy Hモード放電は、NBI加熱とECRHの組み合わせを用いて、より低密度領域で達成される。パワー閾値は密度の減少とともに増加することが見出され、ECRHとNBI加熱パワーの投入順序にはほぼ依存しない。Hモード放電におけるペデスタル密度分布が測定される。ECRHによるポンプアウト過渡位相の間に粒子の外向き対流が観測される。負の密度摂動(ポンプアウト)は、脱ガスによって引き起こされる正の摂動よりもはるかに速く伝播することが観測される。遠方オフアクシスECRHのスイッチオフによって引き起こされるコア電子熱輸送の低減が調査される。低周波帯状流(LFZF)と測地線音響モード(GAM)の共存が観測される。LFZFとGAMの強度の安全係数およびECRHパワーへの依存性が特定される。プラズマフィラメントの3D空間構造が境界プラズマで測定され、磁力線に沿った大規模構造が初めて解析される。大きな磁気島(m-BAE)および高エネルギー電子(e-BAE)によって励起されるベータ誘起アルフヴェン固有モード(BAEs)が観測される。超音速分子ビーム入射(SMBI)の燃料供給効率と侵入特性の研究結果が記述される。
