Abstract: A single-orifice Retarding Potential Analyzer (RPA) has been coupled with a microchannel plate (MCP) of 0.315% transparency to produce viable ion energy measurements within plasma plumes of density greater than 1~1 0 '~ nil, Consisting of several variably biased electrodes, an RPA sensor allows ions with sufficient energy access to a collection plate while repelling electrons and low energy ions. This paper addresses the experimental validation of a Directional microRetarding Potential Analyzer (DpRPA) to a s…
