RF pulses generated by the topside sounder in the ISIS-II spacecraft charge the spacecraft body to a few hundred volts negative. A nonlinear equivalent circuit of the spacecraft body plus dipole antenna has been used to analyze the charge and discharge phases. The ensemble is modeled as a triple probe whose geometric asymmetries are responsible for a net charge being left on system capacitances at the end of the RF pulse. Ambient ionospheric ions discharge the spacecraft during and after the pulse. This discharge has been studied with data from the Soft-Particle Spectrometer, and with supporting evidence from the Ion Mass Spectrometer, the Cylindrical Electrostatic Probe and the Topside Sounder. The access of energetic ions to the detector of the Spectrometer as a function of the angle between the velocity direction and the spectrometer axis is consistent with a quasi-central electric field on the spacecraft upstream side. On the wakeside turbulent particles are attracted back to the spacecraft body within a conic surface centred on the velocity axis.
