摘要
The joint TEXT （J-TEXT） tokamak, formerly TEXT/TEXT-U tokamak, operated by the University of Texas at Austin in USA, has been re-built up in Huazhong University of Science and Technology in China. The machine has been run for two experimental campaigns since 2007. Discharges with plasma current beyond 200 kA and duration of 300 ms have been obtained. At present all sub-systems, such as poloidal field （PF） and toroidal field （TF） power supplies, vacuum system, diagnostics systems etc, are successfully integrated into the routine oper- ation. The plasma position can be elaborately controlled within two centimeters. The operational scenario of J-TEXT are typical of the machine and easily understandable compared to the former TEXT/TEXT-U results.
