摘要: 从状态方程出发,通过四度空间的Maxwell方程协变形式、电磁张量、能量-动量张量在电子注坐标上进行相对论变换,研究了回旋自谐振脉塞的互作用过程,导出了新的互作用状态方程。理论上证明了CARM中工作在TEmn模无纵向电场分量情况下电子注交换纵向能量的机制是存在的。Abstract: From phase equation in an electron cyclotron autoresonance maser (CA-RM) amplifier the interaction between beam and electromagnetic waves is investigated with help of four-dimesional Maxwell equations, electromangetic-field tensor, energy-momentum tensor. The new phase equation is transformed by Lorentz transformation. Being non-longitudinal electro-field component, presence of longitudinal energy change between longitudinal moving beam and TE(Hmax) mode is jutified in theory.
