| Abstract: | The formation of an electron layer and the generation of an electron beam in magnetron guns where secondary emission is triggered by nanosecond pulses are studied. In the guns with small cross sizes, hollow electron beams with an outer diameter of 3–6 mm are generated. The beam current is 1–2 A, and the cathode voltage is 5–7 kV. Results obtained indicate that the generation of nanosecond beam-current pulses is a possibility. |
