Bateman, G

A conceptual design is presented using a combination of superconducting Ripple Reduction Poloidal Field (RRPF) coils together with normal saddle coils in an INTOR-sized tokamak reactor consisting of 8 toroidal field (TF) coils with 7.0 m by 9.4 m active coil bore. The RRPF coils consist of dipole magnetic coils placed between the TF coils and the neutron shielding to produce part of the shaping field needed for a D-shaped plasma equilibrium and to reduce magnetic ripple near the top and bottom of the plasma. They are designed to share the TF coil cryostat and support structure, without obstructing access to the shielding, blanket or first wall. The normal (e.g. water cooled copper) saddle coils are imbedded in the shielding one meter away from the first wall. They carry less than 0.6 MA turns of current and consume less than 16 MW power to reduce magnetic ripple primarily near the midplane of the plasma.
