Ion cyclotron resonance heating in SST-1 tokamak
Multimegawatt ion cyclotron resonance heating (ICRH) system is being developed for the steady state superconducting takamak SST-1 (1), which would form an important heating scheme during non-inductive steady state operation. 1.5 MW of RF power at different frequencies between 22-92 MHz is to be delivered to the plasma for pulse lengths of upto 1000 s. Water cooled antenna, interface and 9 inch Tx-line will ensure safe operation for long pulse operation. Three stages of matching would ensure maximum power coupling to the plasma. Power would be coupled to the plasma through two sets of antennae consisting of two strips in antenna box positioned 180 degree opposite to each other with capability of handling 0.8 MW/m{sup 2} heat load. Electromagnetic stress analysis of the antenna assembly shows that maximum 1.37 kNm torque would be exerted during plasma disruption operating at 3.0 T, 220 kA plasma current. Impurity generation by ICRH antennae is not so severe.
