The objective of this MQP was to complete the design, assembly, and test of a dusty plasma discharge chamber (DPDC) that would be used to evaluate the effect of dust contamination on plasma properties and the effect of the plasma on dust charge. Data are collected using a Langmuir probe and a charge detection mass spectrometer (CDMS). Major improvements were made to the dust contamination dispensing system and the Langmuir probe positioning system. The dust dispenser was redesigned to provide more consistent particle flow rates. Further adjustments were made to the DPDC to enhance its ability to maintain an argon plasma discharge. Preliminary testing was completed and verified the ability to generate a plasma. Both the Langmuir probe and CDMS were integrated with the DPDC and tested.
