Abstract 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 x 1013cm-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 ( 1.0x1013cm-3). These results are not influenced by the current drive directions.
