Abstract

Abstract

Based on the relativistic general trajectory equations solved by the tensor method in a Frenet lecal coordinate system, considering the characteristics of wide electron beam focusing possessing a cathode surface, equations of the principal trajectory and the curvilinear paraxial trajectory are deduced. The characteristics of the curvilinear paraxial system satisfying the orthogonal condition are studied. Problems concerning narrow electron beam focusing or non-relativistic wide electron beam focusing in a curvilinear coordinate system can be regarded as special cases thereof.
