Abstract
Abstract The ion cyclotron resonance heating (ICRH) system of the ignitor machine has been designed. The description of one of the components of the ICRH system, the Faraday shield (FS), and all the relevant calculations are presented in this paper. The thermo-mechanical analysis of the FS is performed. The displacement and stresses due to thermal loads generated by the plasma and dynamic loads induced by plasma vertical disruptions events (VDE) are studied in detail taking into account different plasma scenarios. A final design of the FS that takes into account the theoretical and computational results obtained as well as the qualification for remote handling (RH) positioning of all the FS parts is proposed. A FS split into different compact and easily movable elements is presented.
