    • The influence of probe spacing and probe bias in a double Langmuir probe setup 

      Kjølerbakken, Kai Morgan; Miloch, Wojciech Jacek; Røed, Ketil (Peer reviewed; Journal article, 2021)
      Multi-needle Langmuir probes are mounted on satellites and sounding rockets for high-frequency characterization of plasma in the ionosphere. Mounted on a spacecraft, the recorded probe current often differs from expected ...

    • Numerical Study of Non-Linear Effects for a Swept Bias Langmuir Probe 

      Kjølerbakken, Kai Morgan; Miloch, Wojciech Jacek; Martinsen, Ørjan Grøttem; Pabst, Oliver; Røed, Ketil (Peer reviewed; Journal article, 2022)
      We present a numerical study disclosing non-linear effects and hysteresis loops for a swept bias Langmuir probe. A full kinetic particle in cell (PIC) model has been used to study the temporal sheath effects and the probe ...

    • Sheath formation time for spherical Langmuir probes 

      Kjølerbakken, Kai Morgan; Miloch, Wojciech Jacek; Røed, Ketil (Peer reviewed; Journal article, 2023)
      The formation time of the surrounding sheath of Langmuir probes in an ionospheric plasma has been studied to better understand the constraints this puts on the sampling frequency of a probe. A fully kinetic three-dimensional ...
