    tHigh-frequency (HF) inductive magnetic sensors are the primary ITER diagnostic set for Toroidal AlfvénEigenmodes (TAE) detection, while they also supplement low-frequency MHD and plasma equilibriummeasurements. These sensors will be installed on the inner surface of ITER vacuum vessel, operatedin a harsh environment with considerable neutron/nuclear radiation and high thermal load. Essentialcomponents of the HF sensor system, including inductive coil, electron cyclotron heating (ECH) shield,electrical cabling and termination load, have been designed to meet ITER measurement requirements.System performance (e.g. frequency response, thermal conduction) has been assessed. A prototypingcampaign was initiated to demonstrate the manufacturability of the designed components. Prototypeshave been produced according to the specifications. A series of lab tests have been performed to examineassembly issues and validate electrical and thermo-mechanical aspects of the design. In-situ microwaveradiation test has been conducted in the MISTRAL test facility at IPP-Greifswald to experimentally exam-ine the microwave shielding efficiency and structural integrity of the ECH shield. Low-power microwaveattenuation measurement and scanning electron microscopic inspection were conducted to probe andexamine the quality of the metal coating on the ECH shield
