4. Microwave Gas and Multipactor Breakdown in Inhomogeneous Fields
University dissertation from Göteborg : Chalmers University of TechnologyAbstract : Microwave gas and multipactor breakdown remains to be one of the limiting factors for the maximum power in microwave devices. Above a certain electric field strength, the so-called breakdown threshold, free electrons can multiply by making ionizing impacts with neutral gas molecules, or causing secondary emission upon impact with system surfaces.
