For those of us in the United Kingdom, it can seem like genuine insanity that people would rather see others murdered on a mass scale than have any kind of limit put on their ‘freedom’, but now the ...

Low current density sheet beam electron gun is very useful for compact planar travelling wave tube (TWT). In this paper, a planner low current density elliptical sheet beam electron gun is presented, ...

The sheet beam electron gun is one of the most important parts of a sheet beam traveling wave tube (SB-TWT). In this paper, a 220 GHz sheet beam electron gun is designed and optimized by using CST.
