Plume Characterization of a One-Millipound Solid Teflon Pulsed Plasma Thruster.

摘要

An evaluation was made of the pulsed plasma thruster plume-wall backscatter characteristics of the MOLSINK facility. On the thruster axis, this backscatter drops off to zero as the angle between the axis and wall location reaches 40. This wall backscatter was found to be essentially symmetric about the plume axis. The total integrated backscatter from the MOLSINK wall is approximately equal to 5% of the total mass injected from the pulsed plasma thruster during the discharge pulse.
