Abstract : This report describes work performed during the second year of a contract do analysis in support of three Phillips laboratory flight experiments. The PAsP Plus effort is an examination of the interactions of the PAsP Plus spacecraft and test solar cells with the low-energy plasma environment. This report describes work to develop an analytical model of parasitic current and a preliminary examination of some of the flight data. The SPREE effort is the use of comparison with flight data to examine, improve, and validate sheath and electron collection models and to examine some of the interactions that determine the spectrum of the incident ions. The CHAWS effort is the development and validation of models of the spacecraft wake, including the currents to the various detectors of the CHAWS wake-side sensor on the Wake Shield Facility.
