The data from several previous experiments on the dynamics of the cathode plasma has been analyzed. We show that the transverse expansion of this plasma is affected by the shape as well as the magnitude of the voltage pulse across the diode. Our analysis of the motion of the cathode plasma is based on oscilloscope traces of the electron beam current and of the voltage across the diode. We assume that the electron beam has a hollow structure in a uniform magnetic field when the diameter of the anode of the diode is equal to that of the transport vacuum chamber. The wall thickness of this hollow beam is much smaller than the beam radius and much smaller than the beam radius and much smaller than the anode-cathode gap. (AIP)
