Abstract
A plasma-filled diode is used as a model of the interaction space in a virtual cathode oscillator (vircator). It is shown for a range of values of the positive/negative charge ratio at the entrance electrode (alpha) and the corresponding reduced electrode separation xL the system is capable of generating oscillations. It is also shown that the amplitude of oscillations strongly depends on both (alpha) and xL, although the frequency is largely governed by the value of (alpha) . Such investigations have been previously limited to a single value of (alpha) equals 1, when the positive and negative charge are in balance at the entrance electrode.© (1995) COPYRIGHT SPIE--The International Society for Optical Engineering.
