Summary

A good ion spectrometer for studying the interaction of the solar wind with non-magnetic bodies would have sufficient dynamic range to measure both ionospheric plasmas with temperatures of 300 K and accelerated pickup ions with energies of ≥300 keV, masses between 1 and ≥100 AMU, and charges of −1, +1, or +2; it would also have mass resolution sufficient to separate He++ from H2 + and N2 + from CO+, a 4π ster field-of-view, and time resolution ≈0.2 s. Such an instrument does not now exist and probably never will. A combination of instruments is required to come even close to meeting these requirements. This paper is a survey of some of the techniques which have been used, which are being designed for future missions, or which might be tried to improve measurements of fast ions.
