description: Object of study is polypropylene film 4 microns thick with aluminum sprayed on one side. The aim is studying the characteristics of the radio pulse that occurs during the breakdown of a polypropylene film and based on these data determining the dynamics of the development of breakdown in the film and the features of the formation of the breakdown channel. The breakdown development time of the film under study does not exceed ~500 ns, and the average breakdown strength is estimated at 700Â±20 MV/m. The radio pulse recorded during a breakdown is a damped periodic oscillation of a complex shape. The oscillation spectrum clearly shows peaks at frequencies of 90, 140 and 400 MHz, the amplitude of which changes as the breakdown progresses. A physical model has been proposed to explain the change in the resistance of the breakdown channel and the appearance of spectral peaks in different parts of the oscillograms of radio pulses. When a breakdown occurs, a through channel appears in the film, around which the aluminum electrode partially evaporates. The diameter of the breakdown channel does not depend on the discharge energy and is ~10 Î¼m; the area of the evaporated aluminum layer increases linearly as the discharge energy increases from (5Â±1)â10^3 to (28Â±3)â10^3Â  Î¼m2.
