Abstract
As the beam current in a traveling-wave tube is increased, the local fields due to the bunched beam become appreciable compared with the fields propagating along the circuit. The effect is to reduce gain, to increase the electron speed for optimum gain, to introduce a lower limit to the range of electron speeds for which gain is obtained, and to change the initial loss.
