Torsatron U-2m With Reversed Additional Toroidal Magnetic Field

Abstract

The torsatron U-2M magnetic system is equipped with 16 additional toroidal magnetic field coils. Under normal operating conditions the toroidal field coils create an additional toroidal magnetic field B 0 the direction of which coincides with the direction of a toroidal magnetic field component b 0 generated by the torsatron helical coils on the circular axis of the torus. In the torsatron with reversed toroidal magnetic field (RTF) the toroidal field coils create an additional toroidal magnetic field B 0r of opposite direction. In this study the conditions for developing the magnetic surface configuration with spatial magnetic axis in the torsatron U-2M with RTF are found out and the magnetic surface configuration properties are investigated.
