Excitation of self-sustained secondary emission by gas discharge and hollow beam generation in magnetron injection gun
The electron beam is frequently used for the energy input into the plasma. However, the strong transverse field hampers the charged-particle beam penetration into a closed magnetic trap. This problem can be solved by means of a new electron gun. It is an electron gun with a cold-cathode develope...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | The electron beam is frequently used for the energy input into the plasma. However, the strong transverse field
hampers the charged-particle beam penetration into a closed magnetic trap. This problem can be solved by means of a
new electron gun. It is an electron gun with a cold-cathode developed on the principle of self-sustained secondary
electron emission. In experiments described below the gun ignition was for the first time observed at 2…6 kV direct
voltage in the range of pressures ~ 10⁻²…10⁻¹ Pa. The gun produced the hollow electron beam with current exceeding
1 А and pulse duration up to 1 ms. After ignition the gun can principally operate at any higher vacuum. |
