A Preliminary Study On The Inside And Outside The Slot Penny Tube 3 Harmonic

Peniotron is a fast wave tube devices suitable high power can be generated in the mm wavelength.Compared with the gyrotron more conducive to overcome the mode competition problem,the required magnetic filed is also lower.Penoitron has a very broad application prospects.Russia,the United States,Japan and other European countries in-depth theoretical and experimental study of this device,but to now,relatively few studiea of this particular power vacumm devices in China.So far,research of Peniotron scheme is limited to no inner conductor.In this paper,the3times of the harmonic inner and outer slotted structure Peniotron is studied.First of all,this article describes the research situation and development trend of the Peniotron and Peniotron characteristics and working principle.Use the field matching method derived in detail the characteristic equation of the inner and outer slotted coaxial waveguide and the field expressions.Use self programming mode analyzed the inner and outer slotted coaxial waveguide propagation characteristics.Cold simulation with CST software.Secondly,using non-self-consistent nonlinear theory theoretical analysis the inner and outer slotted structure Peniotron. The use of small signal theory and gentle variable cross-section waveguide resonator theoretical anaysis of the dispersion characteristics of inner and outer slotted structure Peniotron.Got start-up current formula and distribution of longitudinal field.Finally,thecalculation of the load quality factor.Hot simulation of outer slotted structure Peniotron with the MAGIC software.Got the output spectrum,the antenna current,output power and electronic effiency and so on.
