Abstract
The plasma relativistic generator (PRG) at the Sinus 550-80 accelerator has a number of unique properties, such as the single- and multiple-pulse (up to 50 pulses per second) generation modes, generation of microwave pulses with a duration of up to 80 ns and frequencies of 2 to 25GHz, and generation of monochromatic and wide-spectrum radiation. The carrier frequency and the spectrum width can be controlled by varying the experimental parameters, e.g., the plasma density. To investigate the PRG operation modes, appropriate devices for detection of the PRG microwave radiation are needed. In this work, numerical models of antennas with different geometrical parameters are developed using the Ansoft HFSS 13.0 CAD and an antenna with the optimum parameters is proposed for measuring microwave radiation spectra in the desired frequency range at a power level of 50 to 100MW.
