Author(s): K. Narihara Title: A Steady State Tokamak Operation by Use of Magnetic Monopoles Date of publication: Dec. 1991 Key words: Magnetic monopole, current drive, steady state tokamak Abstract: A steady state tokamak operation based on a magnetic monopole circuit is considered. Circulation of a chain of iron cubes which trap magnetic monopoles generates the needed loop voltage. The monopole circuit is enclosed by a series of solenoid coils in which the magnetic field is feedback controlled so that the force on the circuit balance against the mechanical friction. The driving power is supplied through the current sources of poloidal, ohmic and solenoid coils. The current drive efficiency is same as that of the ohmic current drive.
