Some properties of Alfvén waves: Observations in the tail lobes and the plasma sheet boundary layer
[1] We report properties of substorm-related, globally excited Alfvén waves on a temporal scale of 6 to 300 s (3.3 to 167 mHz) at geocentric distances between 5 and 6 RE. The waves were observed in the tail lobes and the plasma sheet boundary layer (PSBL) by the Polar satellite. In each region we made the following observations: (1) The tail lobe Alfvén waves started at substorm onset as determ...
متن کاملPropagation of Alfvén Waves at the Plasma Sheet Boundary Layer
Recently, observations from the Polar and Cluster satellites have indicated that largeamplitude kinetic Alfvén waves are observed throughout the plasma sheet, particularly at the plasma sheet boundary layers, during substorms. These waves may be directly produced by reconnection processes in the tail, or indirectly through linear or nonlinear mode conversion or by localized plasma flows in the ...
متن کاملObservations of Ordered Ion Beams in Cryring
A sudden drop in momentum spread of electron-cooled beams of highly charged Ni and Xe ions, similar to what has earlier been seen at GSI, has been observed at CRYRING. The transition occurs at particle distances between 1 and 35 cm depending on the cooling rate, and it has been interpreted as an ordering of the ion beam. We have studied how the particle number and the momentum spread at the tra...
متن کاملTransient, small‐scale field‐aligned currents in the plasma sheet boundary layer during storm time substorms
We report on field-aligned current observations by the four Magnetospheric Multiscale (MMS) spacecraft near the plasma sheet boundary layer (PSBL) during two major substorms on 23 June 2015. Small-scale field-aligned currents were found embedded in fluctuating PSBL flux tubes near the separatrix region. We resolve, for the first time, short-lived earthward (downward) intense field-aligned curre...
متن کاملSurvey of Galileo plasma observations in Jupiter's plasma sheet
The plasma science (PLS) instrument on the Galileo spacecraft (orbiting Jupiter from December 1995 to September 2003) measured properties of the ions that were trapped in the magnetic field. The PLS data provide a survey of the plasma properties between ~5 and 30 Jupiter radii (RJ) in the equatorial region. We present plasma properties derived via two analysis methods: numerical moments and for...
