文摘The particle confinement property of LHCD(lower hybrid current drive)plasma on the HL-1 tokamak is mainly affected by the line-averaged density of electrons(ne).With ne<2.0 × 10^(13)cm^(-3) the particle confinement time(TP)is improved with the suppression of Hα(Dα)fluctuation at the edge,and tends to increase with the power PLH.The peak of Tp appears near the critical density(1.0×10^(13)cm^(-3)).These results are not influenced by the current drive directions.
