Short summary
This paper describes "beam tracking", a new technology for measuring velocity distributions in the solar wind with a plasma spectrometer, that allows the order of magnitude speedup in data acquisition needed for studying ion-scale turbulence. The basic idea is that the spectrometer should only sample the energy–elevation–azimuth range where the solar wind is expected to reside. The paper shows how the technique can be implemented and illustrates its performance and robustness through simulation.
