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.

Simulation results of multibeam gun for coupled-cavity travelling wave tube have been presented. The code used was the OmniTrak (Field Precision). The results show, that space-charge induced asymmetry ...

We show results of 3D space-charge beam dynamics simulation of an L-Band inductive output tube (IOT) rf electron gun. These results are essential to optimize the interaction circuit potentially ...

In this work the gun design is represented that provides a multiple beam compression on the radius twice and subsequent multiple beam focusing in the 1.5-2 Brillouin fields. The formed multiple beam ...
