摘要
Ion cyclotron range of frequency (ICRF) heating system in EAST is one of the most successful auxiliary heating tools for heating plasmas. Radio frequency (RF) transmitter plays an important role for improving performances of plasmas by using RF wave as a main subsystem of ICRF system. Based on the analysis of electric circuit and theory of transmission line and waveguide cavity, studies on input and output circuit of amplifier, impedance matching between the amplifiers, suppression of the parasitic oscillations and cooling of amplifier cavity were presented. A RF power of 1.5 MW for each was achieved in a matched dummy load during tests of RF transmitters. The RF transmitters operate stably and reliably on EAST and are proved to be competent in EAST ICRF heating experiments.
