Abstract

The structure of an electric field at the cathode edge under emission in the ρ mode in an applied inhomogeneous magnetic field is investigated in the framework of the theory of antiparaxial expansions for a relativistic ribbon beam. Shapes of the lateral surface of a cathode and the negative equipotentials are described, which make it possible to form a profiled expansion gap that does not violate the accepted hydrodynamic model of the flow.

ρ-模式发射下阴极边缘的电场结构

摘要

在相对论带状射束的反傍轴膨胀理论的框架内，研究了在外加非均匀磁场下，ρ模式下在ρ模式下发射时阴极边缘处的电场结构。描述了阴极侧面的形状和负等电位，这使得可以形成不违反公认的流动流体动力学模型的膨胀缝隙。
