The energy-based scaling of a thin current sheet: Case study.
The influence of average plasma energy E~ on the half thicknessℓof a thin current sheet (TCS) is investigated for three cases of TCSs crossings. The value ofℓwas estimated from the magnetic field data by means of Cluster observations. The obtained scaling values for TCSs, Z~=ℓ/ρT, whereρTis the thermal Larmor radius, were compared with the scaling Zμ=22E~/T, where E~ andTare the average plasma energy and the temperature of plasma, which assumes a specific dynamics (conservation of magnetic flux through the trajectory segment) of the current carriers. The comparison of Z~ andZμshows a good agreement.
