Effects of the guard electrode on the photoelectron distribution around an electric field sensor
Miyake, Y.; Usui, H.; Kojima, H.
We have developed a numerical model of a double-probe electric field sensor equipped with a photoelectron guard electrode for the particle-in-cell simulation. The model includes typical elements of modern double-probe sensors on, e.g., BepiColombo/MMO, Cluster, and THEMIS spacecraft, such as a conducting boom and a preamplifier housing called a pu…
Hall MHD simulations of collisionless multiple X line reconnection
Liu, C. X.; Jin, S. P.; Wei, F. S.
A Hall MHD simulation of multiple X line reconnection, in which a diffusion region around the standing X line and the moving plasmoids are involved, is presented. The observed features of Hall magnetic and electric fields in the diffusion region and the direction reversal of the electron flow in the vicinity of the magnetic separatrices are displa…
Wave signatures and electrostatic phenomena above aurora: Cluster observations and modeling
Dandouras, I.; De Keyser, J.; Maggiolo, R. +1 more
This paper reports Cluster high-altitude observations above the acceleration region of a typical monopolar electric field event at the plasma sheet boundary. The observations reveal both characteristics of waves and signatures of electrostatic acceleration. The observations can be interpreted in terms of low-frequency transverse magnetic waves on …

Reduced magnetic helicity behavior in different plasma regions of near-Earth space
Perri, S.; Carbone, V.; Yordanova, E.
We present a comparative study of the scaling laws of a signed measure calculated from the reduced magnetic helicity from Cluster observations in three different near-Earth plasma regions: solar wind, foreshock, and magnetosheath. The reduced magnetic helicity provides information about the handedness of the magnetic field, which can be related to…
