Abstract: ITER is a large-scale scientific experimental device that uses deuterium and tritium as fuel for nuclear fusion reactions and the gas injection system is an important subsystem of ITER. To validate and solidify the design of the GIS based on MFCs, experimental research on the performance of MFCs was conducted, including internal leakage, resistance to static magnetic field interference, flow control accuracy and response time. Furthermore, verification tests were carried out on a vacuum simulation platform for the gas injection prototype. The test results show that the GIS design based on MFCs meets the technical requirements and provides a reference for the operation design of GIS for the ITER, thus providing fundamental engineering data for the GIS design and construction of future fusion reactors.
