Plasma waves and wave—particle interactions seen at the UKS spacecraft during the AMPTE artificial comet experiment

Wave and particle correlator experiments on board the UKS revealed a wide range of plasma wave and wave-particle interactions associated with the 27 December 1984 artificial comet release just outside the main diamagnetic cavity. Shortly after the release strong bursts of plasma waves were recorded, and high-frequency electron oscillations in an enhanced-density plasma were observed later, along with evidence for interaction between a beam of electrons and the local plasma. At lower frequencies, extremely strong wave emissions were associated with what appeared to be the interface between the cloud and solar-wind plasmas.
