Abstract :
A 3-D model of the double slot coupled cavity slow-wave structure (CCSWS) with a solid round electron beam for the beam-wave interaction is proposed in this abstract. Based on the “cold” dispersion, the “hot” dispersion equation is derived with the Borgnis potential function by using the field-matching method. Then, the formula of the linear gain is given.
