Design and Prototyping of Remote Handling Electrical Connector for Diagnostic Rack in ITER

Abstract

The Remote Handling Electrical Connector (RHEC), crucial for in-vessel diagnostics in ITER, enables connection and disconnection through Remote Handling operations. Partitioning electrical lines between the Lower Port sidewall and the Diagnostic Rack, the RHEC connects the Mineral Insulated cable bundle. The design concept omits components like core wire extensions with ceramic sleeves, avoiding overheating and power loss due to impedance mismatching during the mirror cleaning system's plasma generation. The prototype was tested for torque measurements and positional misalignment, proving the RHEC feasibility and remote handling compatibility.
