    One of the main engineering breakthroughs in tokamak device can be obtained by decreasing the excess magnetic flux consumption in the initial plasma production phase. Without this bottleneck, the tokamak designers would be relieved from the yoke of 'the millisecond trial'. The FBX is a spherical torus intended for such a start-up. However in the initial phase, the dielectric breakdown is initiated in the local average minimum B zone and a plasma with an aspect ratio around five is produced. Just as the other tight aspect ratio system, this excessive flux consumption is critical. For the steady operation, she carries six rod-coils to provide poloidal 400 kA plasma current and 0.5 Tesla toroidal field in the magnetic axis. Toroidal multipole field coils are equipped to produce 100 kA toroidal plasma current and 300 eV plasma is sustained in a poloidal diverter formation.
