A self-oscillating electron beam experiment

A recently proposed scheme to persistently over-inject a vacuum electron diode so that it self-oscillates, releasing a periodic train of electron bunches [Leopold et al., Phys. Plasmas 24, 073116 (2017)] was only partially demonstrated [Siman-Tov et al., 26, 033113 (2019)] because of the presence of hot spots on the dispenser cathode surface. The results obtained utilizing a new dispenser cathode with uniform surface emission, produce self-oscillations close to the expected frequencies.A recently proposed scheme to persistently over-inject a vacuum electron diode so that it self-oscillates, releasing a periodic train of electron bunches [Leopold et al., Phys.
