A Method for Solving the Output Current of Traveling Wave Tpube Electron Gun

The formula of electron gun output current establishes the relationship between cathode voltage, grid voltage, anode voltage, filament voltage and electron gun output current. Firstly, the relationship between cathode voltage, grid voltage, anode voltage, and the output current of electron gun is established based on the conductivity coefficient formula. Then, the relationship between filament voltage and electron gun output current is established through filament temperature. Finally, the output current formula of electron gun is obtained.
