Research on a novel compact linac

This work looks at a new type of electron linear accelerator.Compared with the traditional electron linac,it has only two main parts:a klystron and an accelerating tube,without the electron gun element.This new kind of linac could perform just like its predecesors but reduce cost and space.The preliminary design and simulation have been accomplished.In this paper,an overview discussion about the performance tests and some improvements to increase the beam current are presented.
