The Model of Multipactor Discharge Induced by High Power Microwave

Xing-gang LIU,, Ming WEI, Xiao-feng HU


In this paper, a theoretical model of electrostatic discharge induced by high power microwave is established. The mechanism of secondary electron multiplication is analyzed. The secondary electron emission ratio of different materials are compared, and the influence of the electron impact voltage on secondary electron emission ratio is discussed, then we get the change curve of the second electron emission ratio of the different materials. The motion of electrons between two metal surfaces under the action of microwave is analyzed, the velocity of the electron collision on metal surface and the vibration equation of the electrons between two metal surfaces are obtained.
