| Summary: | BackgroundElectron cyclotron resonance heating (ECRH) is an important heating and plasma current control method for the HL-3 tokamak. Microwave inject into plasma through the launcher, which is an important part of the ECRH system. The ECRH launcher system of HL-3 tokamak consists of three launchers, including a mid equatorial launcher and two upper launchers. All launchers are located in the same sector, and can work together to complete functions such as heating and Neoclassical Tearing Mode (NTM) control.PurposeThis study aims to design and test the ECRH launcher system of the HL-3 tokamak.MethodsFirst of all, the overall planning was carried out for the launcher system. Subsequently, the transmission path and structure of the launcher were designed, and the effect of microwave injection were calculated by simulation. Then, detail design and implementation for the mid-equatorial launcher and No.1 upper launcher were completed, so did the optical path design for No.2 upper launcher. Finally, the transmissio |
