Heating profiles on ICRF antenna Faraday shields

A conceptual design for an uncooled Faraday shield for the BPX (Burning Plasma Experiment) ion cyclotron resonance heating (ICRH) antenna, which should withstand the proposed long-pulse operation, has been completed. A high-heat-flux, uncooled Faraday shield has also been designed for the fast-wave current drive (FWCD) antenna on DIII-D. For both components, the improved understanding of the heating profiles made it possible to design for heat fluxes that would otherwise have been too close to mechanically established limits. The analytical effort is described in detail, results of analysis are shown, and configuration issues involved in component modeling are discussed.<
