A 220 GHz double-anode sheet-beam electron gun with a circular cathode is designed using the three-dimensional particle simulation software Opera 18R2. The simulated results of beam current and the size of the beam waist are 140 mA and 0.5 mm×0.1 mm at z=9 mm, respectively. This proposed double anode sheet beam electron gun is used in a T-shape staggered double-grating traveling wave tube (TWT).
