Full superconducting tokamak and water-cooling Cu magnets tokamak are two options proposed for China Fusion Engineering Test Reactor (CFETR). Based on the concept design, the total construction cost was assessed with System Analysis Program for Parameters Optimization and Economic Assessment of Fusion Reactor, and the economy of the two options was compared with considering the cost of electricity...
To energize the gyrotrons of the electron cyclotron resonance heating system, high-voltage power supply (HVPS) at 100 kV/60 A was built on J-TEXT tokamak. The HVPS was based on pulse step modulation (PSM) technology. This power supply has many advantages, including low energy storage and a short protective time in the event of a short circuit fault. In this study, we analyze and compare several common...
