An experimental system of foilless diode operating in low guiding magnetic field was designed on the pulsed power generator S-5N. In the experiment, a trapezium-shape wavefrom was obtained with a rise time of about 9 ns and a flat top of about 26 ns when magnetic field strength was 0.5 T. The diode voltage was 420 kV and the current was 2.7 kA. The average radius of the beam spot was 16 mm. There was a good agreement between the design and experimental results. It was observed that the diode impedance increases following the guiding magnetic field until it reaches a turning point.
