This work reviews the progress in the area of high current density electron emitters,
specifically for use in high frequency and high-power microwave vacuum electron devices …

A barium tungsten (Ba-W) cathode was successfully prepared with spherical W powder in
this letter, and the porous matrix exhibited homogeneous pore distribution and good inter …

The porous tungsten matrixes of barium tungsten cathodes are prepared by spark plasma
sintering (SPS). By adjusting the raw powder particle diameter and the porosity, the matrixes …

In this research, porous W matrixes for dispenser Ba-W cathodes were prepared by metal
injection molding (MIM) using W powders with different particle shapes as raw materials …

利用正交试验探讨了放电等离子技术工艺参数(温度, 压力, 保温时间) 对钡-钨(Ba-W) 阴极中的W
的孔隙度的影响规律, 获得了孔隙率在23%~ 30% 内变化时所需要的最佳工艺参数. 在此基础上 …

There is a requirement of free electrons in any kind of vacuum electron device. The source of
free electrons is called the cathode, which generates the required amount of electron …

A mathematical model was developed to estimate the dynamic coverage of barium on the
surface of a controlled-porosity dispenser (CPD) cathode. This model considers the …

We regret to inform that there had been some serious omission regarding the information of
