Moment of injection of runaway electrons at the front of accelerating pulse in air-filled diode with inhomogeneous field: From instability to determinacy

A simple method is proposed that makes it possible to determine the moment of injection of a bunch of runaway electrons relative to a subnanosecond leading front of the accelerating high-voltage pulse applied to the cathode in air-filled diode with inhomogeneous field. The moment of injection is det...

Summary:A simple method is proposed that makes it possible to determine the moment of injection of a bunch of runaway electrons relative to a subnanosecond leading front of the accelerating high-voltage pulse applied to the cathode in air-filled diode with inhomogeneous field. The moment of injection is determined by finding a minimum in dispersion of the time delay between the variable point of oscilloscope sweep triggering on the instable front of the accelerating voltage pulse and the detected front of the electron current pulse.
