| Summary: | 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. |
