Transmission technigue of repetition pulse and intense current electron-beam

The stability condition of intense annular electron beam transmission is analyzed and deduced. Based on the static electric-magnetic field simulation, the position and configuration of the guide magnetic-field and its magnitude as well as its power supply are designed. Then the experiments of repetitive rate and inte nse current electron-beam diode are carried out on CHP01 generator, and the ima ge of the intense annular electron beam is measured too. The results show that t he designed 1-s magnetic field satisfies to the stability condition of intense annular electron beam transmission. It can stably transmit intense current elect ron-beam pulse of 800kV/8kA, pulse width 40ns, repetition rate 100Hz. And now t he 1-s magnetic-field system is successfully used on CHP01 accelerator.
