Translation of a Field-Reversed Configuration (FRC) into a quasi-spherical confinement region with super-alfvénic translation speed has been successfully conducted. Translation speed can be controlled in the range from 80 to 150km/s by changing statically filled gas pressure. The translated FRC experiences radial decompression process rapidly when it enters into the confinement chamber. The separatrix shape of translated FRC is controlled through the translation process. Especially, in the case of FRC translation into deuterium gas atmosphere, elongation of the FRC is roughly unity. It indicates possible application of center solenoid onto the high-beta compact torus of FRC. Also, as a new finding, a rotational instability with an n=2 deformation has been observed in the translated FRC.
