The electron optics system (EOS) includes electron gun, focusing system and collecting pole, which is the key part of the traveling wave tube (TWT). In this paper, the EOS suitable for 0.67 THz TWT is ...

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.
