Electro-mechanical connection system for ITER in-vessel magnetic sensors

摘要: Abstract This paper presents the preliminary design of “In-Vessel Magnetic platform”, which is a subsystem magnetic diagnostics formed by all components necessary for guaranteeing thermo-mechanical interface actual sensors with vacuum vessel (VV), their protection and electrical connection to in-vessel wiring transmission detected signal minimum level noise. The has been developed in order comply different functional requirements: mechanical attachment VV; wiring; efficient heat transfer compatibility Remote Handling (RH) system replacement; integration metrology features post-installation control; Electro Interference (EMI) shielding from Electron Cyclotron Heating (ECH) stray radiation without compromising sensor pass band (15 kHz). Significant effort dedicated develop CAD model, integrated within ITER In-Vessel configuration taking care geometrical compliance Blanket modules (modified accommodate suitable grooves) RH compatibility. Thorough electro-magnetic Finite Element Method (FEM) analyses have performed assess reliability standard off-normal operating conditions low frequency sensors.
