| Abstract: | The sheet beam relativistic extended interaction oscillator is a very important high power microwave source with many actual and potential applications. Based on the electromagnetic simulation software and 3D PIC code, a Ka-band sheet beam relativistic extended interaction oscillator is designed. A sheet electron beam with a width-to-height of 30 is adopted to reduce the space charge effect. In order to increase the power capacity of the device, the extended interaction cavity is selected as the high frequency structure. In the PIC simulation, when the beam voltage is 400 kV and current is 2 kA, the device can generate a 240MW output power at 30GHz with an efficiency of 30%. |
