Design of a 4D Emittance Measurement Device for High Charge State ECR Ion Sources

The principle of design and calculation of the power synthesis in the solid-state amplifier are described in this paper.The working frequency of the synthesizer is 80.5 MHz.The output continuous wave power is more than 20 kW;The synthesizer power capacity is analyzed.The theoretical calculation results,Computer Simulation Technology(CST) simulated results are compared with the measured results of the actual 3 dB couplers.The analysis of the measured results and CST calculated results shows that the simulation is in agreement with the measurement results which meet the design requirements of the solid-state amplifier.Except the coupling coefficient,the isolation,the VSWR and other parameters are better than the design target.When the output power is 20 kW,the sampling waveform has no deform and the temperature of the synthesizer is stable.
