摘要：
We have operated an electron gun using a ferroelectric cathode at a diode voltage of 450 kV. The beam current and its waveform have been studied under various triggering conditions. Adjusting the amplitude and applied timing of the trigger pulse has led to a unique method of current pulse shaping for the ferroelectric diode. The method is convenient and the beam current with a reasonable pulse shape is achievable even with a relatively poor condition of the voltage pulse. Optimum conditions for applying the trigger pulse have been determined and the beam current with the required shape is obtained.
