Density Derivation Using Controlled Spacecraft Potential in Earth's Magnetosheath and Multi‐Scale Fluctuation Analysis

Abstract

High time resolution electron density is derived from spacecraft potential on Magnetospheric Multiscale during operation of the ion emitters • The high time resolution allows to study plasma density fluctuations down to the sub-ion kinetic scale • An increase of magnetic field and density anisotropy is found that indicates the presence of compressive structures in the magnetosheath
