Energy confinement time taken from 135 discharges of the 2006 campaign inHL-2A is studied.The data obtained from the measurements are verified by comparing diamag-netic energy with the electronic kinetic energy calculated from both the electron temperature anddensity profiles.Two data sets for supporting the ITER L-Mode confinement database are gener-ated from the 2006 campaign.The dependence of ΥE on the line-averaged electron density duringohmic phases is analysed.The comparison of ΥE in electron cyclotron resonance heating(ECRH)plasma as well as the existing ITER L-mode scalings is made.The results show that the energyconfinement time is consistent with the ITER L-mode scalings.
