Paper Abstract

In this paper the physical mechanism and mathematical description of magnetically self-focusing electron beam are studied.The analysis of electron beam with weak pulsation in drifting tube filled with plasma was given,the beam with strong pulsation under the same condition was also studied accurately.The results show that whether in (alpha) area or in (beta) area both the range and wave length of beam pulsation related to initial condition and plasma parameters although their pulsation properties were different,there exited a optimum plasma density when the other condition was set.The experimental studies are also reported of beam transmission in plasma channel based on Hollow Cathode Plasma(HCP) gun in University of Electronic Science and Technology of China(UESTC).The study shows that efficient transmission of electron beam in plasma channel can be reached by choosing the plasma filling factor and voltage.
