Study on 1.5MW RF amplifier for EAST ICRF heating system

CHEN Gen,MAO Yu-zhou,ZHAO Yan-ping(Institute of Plasma Physics,Chinese Academy of Sciences,Hefei 230031)  
Preparations for the final power amplifier of the 1.5MW RF source were discussed in the EAST ICRF heating system with a wide frequency range of 25 to 70MHz.The wide-band,high-power,steady-state RF amplifier will be illustrated from three main aspects: the optimized operating parameters,input circuit,and output circuit.The analysis of this amplifier is in agreement with test results.It could be a foundation for the reliable operation of ICRF heating system.
