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 ...

This paper presents the design and verification of the electron optics system (EOS) for D-band Travelling Wave Tubes (TWTs). The electron gun generates a beam current of 57 mA at a beam voltage of ...
