Relativistic electron-beam generation in a plasma-filled diode and its interaction with plasma
Abstract
A relativistic electron beam of 150-300 keV, 1-2 kA, and 40-80 ns generated in a plasma-filled diode is injected into a magnetized hydrogen plasma of density 1011-1014 cm-3. Beam-plasma interaction was observed to be strong when the plasma density in the diode and interaction region was ≂1012 cm-3. The effective collision frequency was estimated to be around 10-2 times the ion plasma frequency. The plasma heating levels of ≂1016 eV cm-3 μs-1 were inferred. The observed net current multiplication was explained by two-stream instability.
