Pulsed Plasma Thruster Plume Measurements Using a Triple Langmuir Probe Method

Abstract A current-mode triple Langmuir probe method was developed and used to measure electron temperature and density in the plume region of a laboratory model Teflon pulsed plasma thruster. This experiment was performed in a large vacuum facility at base pressures of 5 1 Torr. Measurements were taken at a range of positions from between 10 and 20 cm downstream of the Teflon 7 0 2 10 − × − × 6 −
