Description
6 MW will be coupled to the plasma by using four strap antenna in KSTAR (Korean Superconducting Tokamak Advanced Research) ICH system where 8 MW rf power is launched from the transmitter in the frequency range from 25 to 60 MHz. There are two important factors in the design of KSTAR ICH system. One is the breakdown voltage in the transmission system which limits the maximum rf power coupled to the ICH antenna and another is the removal of the heat from the rf ohmic loss during the long pulse operation. Maximum breakdown voltage and current in ICH system are 35 kV and 1kA, respectively and components are designed for the operation of 300 seconds. The test bed is designed to produce at least 35 kV/1 kA by applying low rf power up to 30 kW and high voltage/current test is performed on the vacuum feedthrough and other transmission components
