We propose an experimental scheme of and develop a method for studying a one-sided multipactor discharge in crossed fields in the saturation regime. Basic parameters of the discharge have been measured. In the experiment performed in a 3-cm wavelength band, the discharge develops in microwave fields with intensities from 8 kV/cm (near the lower threshold) to 20 kV/cm and became stabilized during at least a hundred cycles of multiplication of secondary electrons on the discharge surface. In this case, the maximum power absorbed in the discharge amounts up to 4 kW/cm2, and the corresponding density of the saturated-discharge current, up to 10 A/cm2. The measured time of discharge development is equal to 15–30 ns. These parameters agree well with estimating calculations based on approximate analytical models.
