A radial insulated diode with a high emission current density of electron-beam was introduced in this paper. As an experiment platform, the CHP01 accelerator was used to study the emission characteristics of the diode. This intense current electron-beam diode can operate steadily at the pulse repetition rate as high as 100 Hz. The beam voltage exceeds 600 kV, beam current 12 kA, pulse width 45 ns. Correspondingly the emission current density of cathode is as high as 17 kA/cm2. The characteristic impedance of diode as a function of magnetic-field was studied.
