A self-sustained state driven by the bootstrap current was achieved in JT-60U. Based on a high confinement reversed magnetic shear plasma, a plasma in which the bootstrap current frafciton of almost 100 percent (plasma current 
0.55 MA) was successfully maintained for 2.5 s. The dynamic response of a completely self-driven system with negligible external current drive was studied. Repetition of beta collapses and recoveries were often observed. Furthermore, discharges in which the bootstrap current fraction can be expected to be larger than 100 percent were obtained.

Times Cited Count：12 Percentile：38.70(Physics, Fluids & Plasmas)This papaer studies on tokamak plasma start-up completely without central solenoid (CS). On the JT-60 tokamak it is demonstrated that a completely CS-less Ip start-up to 100 kA was achieved even without any null-point by Electron cyclotron range of frequencies (ECRF) and outer PF coil current swing only. Necessary conditions (the EC power, the toroidal field etc.) were clarified. Moreover, it was succeded to maintain Ip = 260kA for 1 sec without CS by NB only. In addition Ip ramp-up by EC and NB only (without LHCD) from 215 to 310kA was achieved. In a high confinement reversed shear discharge, a result suggesting bootstrap over drive was obtained.
