摘要: In order to study the physical mechanism of an oscillation newly discovered by Harbin Institute Technology Plasma Propulsion Lab (HPPL) in range hundreds kHz several MHz, Hall thrusters with different magnetic coils are studied changing one following three parameters: discharge voltage, anode flow and coil current, directly measuring current plasma oscillations related Langmuir probe. Experimental results indicated that process a thruster broadband turbulence causes unstable spatial field this circuit resonate as equivalent high level resistance?inductance?capacitance (RLC) network. As response network, has large oscillating component at natural frequencies Also, effect on same time, so they reach self-consistent equilibrium state. result such coupling, both exhibit their circuit. It is therefore concluded caused coupling between
