Description
The microwave generator based on a magnetron generator with inverter sources of anode voltage for use in ECR sources of light ions is presented. The anode power source of magnetron is built according to the scheme of a quasi-resonant bridge converter with phase control at conversion frequency of 100 kHz. DC magnetron filament power supply with the possibility of smooth voltage adjustment has been developed to reduce the level of pulsations of the output microwave power. Generator power can change from 100 watts to 750 watts continuous regime when using an available magnetron at frequency of 2450 MHz. The dependence of the energy and frequency characteristics of magnetrons on inverter power sources with the ability to adjust the microwave power are studied. As a result of the research, it was noted that the bandwidth of the generated microwave power does not exceed 2 MHz. The project of such generator for the ion source ECR has been prepared.
