    • Ion Cloud Expansion after Hypervelocity Dust Impacts Detected by the MMS Electric Probes in the Dipole Configuration 

      Vaverka, Jakub; Pavlů, Jiří; Nouzak, Libor; Šafránková, Jana; Nemecek, Sdenek; Antonsen, Tarjei; Mann, Ingrid; Lindqvist, Per-Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-11-08)
      Dust impact detection by electric field instruments is a well-established technique. On the other hand, not all aspects of signal generation by dust impacts are completely understood. We present a study of events related to dust impacts on the spacecraft body detected by electric field probes operating simultaneously in the monopole (probe-to-spacecraft potential measurement) and dipole (probe-to-probe ...

    • One-Year Analysis of Dust Impact-Like Events Onto the MMS Spacecraft 

      Vaverka, Jakub; Pavlu, Jiri; Nouzak, Libor; Safrankova, Jana; Nemecek, Zdenek; Mann, Ingrid; Ye, Shengyi; Lindqvist, Per-Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-16)
      We present an analysis of 1‐year data of dust impacts observed on two of the Earth‐orbiting Magnetospheric Multiscale mission (MMS) spacecraft. The dust impact signals were identified in observations of the electric field probes and were registered simultaneously by monopole and dipole configurations of the instrument. This unique setup allows us to reliably identify changes in the spacecraft potential ...
