To Make Devices for Superconducting Coil Voltage Measurement
The National Fusion Research Institute announced on Dec. 29 that its consortium including Mobiis and JH Engineering won a 5.6 million euro ITER project and the project is to design and build a high voltage signal processing system for superconducting coil quench detection.
The consortium is supposed to make components and devices for superconducting coil voltage measurement and those will be supplied to the ITER construction site in Cadarache, France after testing procedures.
A superconducting coil generates a strong magnetic field for ultra-high temperature plasma containment. In the event of quenching during operation, that is, a switch from an ultra-high temperature state to a normal conducting state, the magnetic field energy may turn into thermal energy and damage may arise. A high voltage signal processing system is required in this regard so that the presence or absence of quenching is found based on superconducting coil voltage and temperature measurement.
“We have won a series of ITER projects by cooperating with domestic companies,” the institute said, adding, “We are anticipating that this will continue based on close collaboration.”
