The external circuit effect on the steady states of a vacuum diode with a decelerating electron beam

It was found out that a reactive load presence in the external circuit of a diode with an electron beam can crucial change its operation modes. Using a non-relativistic Bursian diode with a decelerating electron beam as the example, it was demonstrated that the presence of inductance in the external circuit leads to the development of instability in the diode-external circuit system. Values of the parameters for which the diode can generate oscillations are determined. The instability growth rates and frequencies are calculated. (paper)
