Abstract : The interaction of charged particles with the electrostatic and flow fields surrounding a rocket-borne mass spectrometer is considered. The objective is to relate the ambient density of various ionic constituents of the ionosphere to the corresponding currents reaching the spectrometer orifice. The interaction is analyzed at low altitudes where space charge effects can be neglected and at intermediate altitudes where these effects are dominant. At high altitudes, older results corresponding to free molecular flow are applicable. The performance of the device in measurements of negative ions is considered from the point of view of the double probe theory. (Author)
