A magnetic divertor incorporated into a central solenoid of GDT is considered as an alternative MHD stabilizer for axisymmetric high- plasma. The divertor magnetic field structure can be produced by addition of several new coils to the present coil system in the region occupied by a hot-ion population. The important constraints on the divertor magnetic field are discussed. It must naturally fit into the GDT magnetic field and neutral beam geometry, should be adjustable to the plasma and allow for easy recovery of the standard operational regimes.
