TEXT/(TEXT- u)托卡马克原由美国德克萨斯大学奥斯汀分校建造和运营，于2004年拆除并运往中国，并更名为联合TEXT （J-TEXT）托卡马克。重建工作，包括重新组装机器和开发外围设备，已于2007年春季完成。因此，在2007年底获得了第一个等离子体。目前，典型的J-TEXT欧姆放电可以产生平顶电流高达220 kA，持续时间为300 ms的等离子体，线平均密度在2 × 1019 m−3以上，电子温度约为800 eV，环形磁场为2.2 t。在J-TEXT托卡马克上开发了许多用于日常操作和实验场景的诊断设备。因此，对边缘区域的静电波动进行了测量，并对最后一个封闭通量面附近的间歇爆发事件进行了条件分析。对MHD活性和破坏事件进行了观察和简单分析。详细介绍了J-TEXT的初步实验结果和未来的研究计划。
The TEXT/(TEXT-U) tokamak, formerly built and operated by the University of Texas at Austin in USA, was dismantled and shipped to China in 2004, and renamed as the Joint TEXT (J-TEXT) tokamak. The reconstruction work, which included reassembly of the machine and development of peripheral devices, was completed in the spring of 2007. Consequently, the first plasma was obtained at the end of 2007. At present, a typical J-TEXT ohmic discharge can produce a plasma with flattop current up to 220 kA and lasting for 300 ms, line-averaged density above 2 × 1019 m−3, and an electron temperature of about 800 eV, with a toroidal magnetic field of 2.2 T. A number of diagnostic devices used to facilitate the routine operation and experimental scenarios were developed on the J-TEXT tokamak. Hence, the measurements of the electrostatic fluctuations in the edge region and conditional analysis of the intermittent burst events near the last closed flux surface were undertaken. The observation and simple analysis of MHD activity and disruption events were also performed. The preliminary experimental results and the future research plan for the J-TEXT are described in detail.
