ICRF coil for the IDEAL plasma

We describe an ICRH coil to drive the plasma in the proposed IDEAL device, a linear plasma machine designed to study the physics and engineering problems of the ITER divertor. In initial operation, 2 MW of CW power at ∼40 MHz will be applied to a hydrogen plasma via four 0.75‐m long multiple saddle coils that excite ICRF slow waves. The waves propagate to a 30 % magnetic beach, where they undergo cyclotron absorption. At full heating power the power flow out the ends of IDEAL is designed to equal that in the ITER divertor. Coil loading and the radial distribution of the E+ and E− RF fields have been calculated with the ANTENA Code.
