Analysis of higher-order modes of multipactor in magnetically insulated transmission line oscillator

Based on the physical analysis of the multipactor for magnetically insulated transmission line oscillator (MILO)， the higher-order resonance modes of multipactor in MILO are analyzed and calculated.The results show that the susceptibility region, in which the multipactor occurs, of the higher-order resonance modes is much smaller than that of the basic resonance mode. so the multipactor discharge is more importance of the basic mode than of the higher-order modes．
