在硅化后的良好器壁条件下，采用慢斜升放电模式，获得了具有高电流密度和较高温度的反场箍缩（ＲＦＰ）等离子体。在实验中观测到环向磁通长时间持续增长，随等离子体电流增大而增大，并出现与环向磁通相伴随的ＭＨＤ扰动现象。实验证实，斜升放电的ＲＦＰ等离子体存在“发电机”（ｄｙ－ｎａｍｏ）效应。ＲＦＰ位形维持时间长达８００μｓ，等离子体电流约１００ｋＡ，电子和离子温度分别达到７０ｅＶ和８５ｅＶ。
Under the good wall condition after the silicidation, a slow ramp-up discharge mode was used to obtain the RFP plasma with high current density and high temperature. In the experiment, it was observed that the toroidal flux continued to grow for a long time and increased with the increase of the plasma current, and the MHD perturbation accompanied with the toroidal flux appeared. Experiments have shown that there is “dy-namo” effect in RFP plasma generated by ramp-up discharge. RFP shape retention time up to 800μs, the plasma current of about 100kA, electron and ion temperature reached 70eV and 85eV.
