(a) Outline of the NUCTE-III experimental device used for the translation experiment. (b) Axial profile of the guide field. The solid and dashed lines indicate the guide field without and with translation, respectively.
Time evolution of the guide field produced by the theta-pinch coil (a), and the auxiliary coil current without translation (b) and with translation (c).
Time evolution of the axial separatrix radius profile without translation (a) and with translation (b). The separatrix radius is obtained by the excluded flux measurement. Hatching regions indicate observed FRCs in the cases with and without translation.
Time evolution of typical plasma parameters: (a) total inventory, (b) poloidal flux, (c) total temperature, (d) stored energy, and (e) kinetic energy. The position of the interferometer is denoted by the symbols ◻: , ○: , △: , ▽: , and ◇: . The dashed lines represent the time evolution of each plasma parameter with translation, linearly fitted.
