Design and development of ECRH/ECCD system on HL-2M tokamak

According to heating requirements of HL-2M physical experiments, the electron cyclotron  resonance heating and current driven (ECRH/ECCD) system with a total power of 8MW was designed. Key  components, such as wave source, transmission lines and antennas were developed. The 8MW ECRH/ECCD  system consists of 8 sets of 105GHz/1MW/3s wave source systems, 8 vacuum transmission lines with 63.5mm  inner diameter and 3 sets of real-time feedback control antennas. At present, key components for ECRH/ECCD  system were finished and the relative desktop and high-power tests were carried out. The results show the output  power of the wave source-gyrotron reaches 1MW/3s, which can be transported by the evacuated over-mode  corrugated circular waveguide transmission line with the vacuity of 10?2Pa stably with low power loss, and the  response time of the antennas in full range of injection angle in poloidal direction is less than 50ms.
