  grid mesh
Nonmonotonic potential distribution in a grid mesh of a plasma switch
      
To eliminate discrepancies between the analysis and experiment, it is assumed that the potential (virtual cathode) distribution in a grid mesh is nonmonotonic in the direction of current transfer.
      
Based on previous results, the most probable potential distribution in a grid mesh and near the grid of a plasma switch is presented for the case when the discharge current passes through the grid.
      
The ratio of the membrane thickness to the grid mesh reaches 1: 1000.

The effects of variable load on the abrupt change of power output and discontinuity of oscillation of a. reflex klystron are investigated. The reflex klystron under study is of metal construction with integral resonant cavity operating in the "X" band.Analysis is made of the effects of overload, long line, multiple transits of electrons, parasitic resonance and imperfections in the design of the integral resonator.Among the factors which affect the load characteristics the most important one is shown to be the...

The effects of variable load on the abrupt change of power output and discontinuity of oscillation of a. reflex klystron are investigated. The reflex klystron under study is of metal construction with integral resonant cavity operating in the "X" band.Analysis is made of the effects of overload, long line, multiple transits of electrons, parasitic resonance and imperfections in the design of the integral resonator.Among the factors which affect the load characteristics the most important one is shown to be the design of the resonator, especially that of the distribution of side and gap capacitances as well as the curvature of the grids in the gap.The theory of parasitic resonance is briefly treated, and the experiments which have been performed to locate the parasitic resonance are described. Finally, a method of eliminating the parasitic resonance is illustrated.

本文叙述了某X波段金属内腔反射速调管的振荡功率曲线随负载变化时出现的凹坑或振荡中断现象,在分析该现象出现的原因时,应区分是由于电子多次渡越造成的迟滞现象、长线效应、负载过重、寄生诸振,还是由于谐振腔设计上的缺陷。 文章指出,在影响负载特性的诸因素中,谐振腔的设计,尤其是中央突起部分的隙缝电容与旁侧电容的合理分配,以及构成高频隙缝的栅网曲率最为重要。 文章简要介绍了寄生诸振的理论,指出了消除寄生造振的途径,并举出实例说明解决的方法。

The concentric spherical electro-magnetic focusing system as an imaging system was described at the Second Symposium on photo-electronic Image Devices, but was not fully discussed; up to now the analytic solution for the electron trajectories in this system hasn't been given. In this paper, the concentric spherical electro-magnetic focusing system together with three other systems, namely, the electro-magnetic focusing system using parallel homogeneous magnetic and electric fields, the concentric spherical electrostatic focusing system and proximity focusing system are studied, the analytic solution for "paraxial" trajectories, the focusing condition and the spherochromatic aberrations are given, and the concentric spherical electrostatic focusing system with spherical mesh and the electro-magnetic focusing system with planar mesh using parallel homogeneous magnetic and electric fields are also discussed.
