Plasma Relativistic Microwave Noise Amplifier with the Inverse Configuration

The results of numerically simulating a high-power plasma maser-the wideband microwave noise amplifier-are reported. The configuration and parameters of the device are chosen with a view to its possible future use for generating pulses with a duration of 3 ns and pulse frequency bandwidth of 0.3 to 2 GHz. In the pulse-periodic mode, it is possible to generate radiation in a continuous range of 2 to 12 GHz with an average pulse power of 20 MW and pulse energy efficiency of 6%.
