| Zusammenfassung |
| In-situ measurements of the electron diffusion region (EDR) during magnetic reconnection are essential to our understanding of energy dissipation in collisionless plasmas. The Magnetosphere Multiscale mission consists of four spacecraft in a tetrahedron formation with an average inter-spacecraft separation as small as 2-5 electron inertial lengths, allowing for the first time a multi-satellite exploration of the EDR. We study the EDR at the magnetopause under a variety of plasma and field asymmetries, particularly density, to understand how the thickness of the dissipation region scales as a function of local and upstream parameters. Current density and energy dissipation are computed using both spatial gradient techniques and individual spacecraft measurements. The thickness of the dissipation region is then compared over several encounters of the EDR. |
