【 摘 要 】

We present the results of rf oscillations growth dynamics as the high voltage pulse propagates through the gyromagnetic nonlinear transmission line (NLTL). Several equidistant electrical probes were placed inside the NLTL in order to examine the oscillatory wave formation and the role of higher order modes in this process. RF pulses are generated at 2 GHz frequency with nonaveraged peak power of 100 MW. Azimuthal asymmetry of the wave propagating through NLTL is detected.
