Abstract:
An experimental study was conducted to analyze the effect of side screen geometry in a diode-based voltage stabilizer on plasma-beam electron energy relaxation. The results demonstrate that using a conical screen configuration provides for a gradual increase in energy relaxation length and a multi-fold increase in current density. Parameters such as helium pressure, interelectrode gap, and electrokinetic characteristics were optimized. Effective voltage stabilization was achieved within the range of 20 to 65 V at current densities of approximately 2 A/cm$^2$.
