“…The images show significant differences in structures for different orientations of the IMF, primarily at the front boundary and in the tail region. The structure of the magnetotail has been investigated in a laboratory simulated magnetosphere (Birn et al 1992;Yur et al 1999). The locations of the magnetopause x = 9 cm and x = 10 cm for northward 200 G and southward -200 G IMF respectively that corresponds to the location shown in the photographic image of Fig.…”

“…The voltage-biased Faraday cups (-50 to -100 ~V bias) are used to measure ion current density, ion time-of-flight (TOF) velocity (using cups located in sequential ports), plasma beam density (from the velocity), and the beam divergence (by scanning the beam cross section at various downstream locations). We have fabricated very small two-sided Faraday cups that will be used for determining the net flow of plasma in the magnetotail region (Yur et al 1999). …”

“…This unique experiment is not exact simulation of the magnetosphere but does address the formation of each region of the magnetosphere in space physics. The tail region has been studied at the UCR laboratory and observed the X-type and Y-type tail structures for the southward and northward interplanetary magnetic fields (IMF) respectively (Birn et al 1992) and (Yur et al 1999). Therefore, we give our attention to the front region of the magnetosphere without comparing the entire global features with the planetary-magnetosphere structures.…”

A laboratory experiment was conducted to investigate the interaction between a plasma beam and a magnetic dipole, simulating the interaction between the solar wind and magnetized planets. The emphasis in this paper is on the laboratory simulation in the front region of the Earth's magnetosphere and their variation under different solar wind conditions. The boundary in the front region of the magnetosphere is observed in a space simulation laboratory and the magnetospheric structure is produced by a super-Alfvénic and collisionless plasma beam interacting with terrella field. The boundary of the magnetosphere is determined by the factors that include solar wind parameters, such as magnetic fields, ion current density and magnetospheric structure images. It is interesting to compare the results of laboratory simulations with the empirical model by Shue et al. (1997) and the theoretical model by Cheng (1998) as well for the prediction of magnetopause locations under any solar wind condition. The comparisons show that for the northward IMF, magnetopause locations in the laboratory simulation are consistent with the theoretical model. As the magnitude of northward IMF B z becomes higher, the subsolar distance and the flank position in laboratory simulations are consistent with the empirical model as well. For a lower southward IMF B z , magnetopause locations in laboratory simulations are consistent with both the empirical and theoretical models. As the magnitude of the southward IMF B z becomes higher, the subsolar distance and the flank position in laboratory simulations seem closer to the theoretical model than the empirical model.

“…For example, the structure of the inner magnetosphere, the formation of current systems in it, and charged particle precipitations into the auroral region were studied in [29][30][31]. Simulations of the large scale structure of the magnetosphere with the shock wave, magnetopause, magnetotail, and magnetic reconnec tion region on the night side were described in [32][33][34]. The dependence of the magnetotail configuration on the interplanetary magnetic field was determined in [33], while the formation of plasma bulk flows in the magnetotail was investigated in [34].…”

“…In addition, artificial plasmas can be produced by a plasma source (inflated bubble concept). Such an experiment can open up the possibility of studying experimentally the physics of two counter-streaming plasmas in an open and boundary-free environment that cannot be realized in the laboratory where boundary conditions strongly constrain the dynamics of the plasma [6][7][8][9]. By controlling the physical and geometrical parameters of the plasma tied to an Earth orbiting satellite we can study the spatial structure of the configurations that the two plasmas can attain, the onset of the instabilities that their relative motion can cause and the plasma turbulence that can result from the development of these instabilities.…”

A study supported by the European Space Agency (ESA), in the context of its General Studies Programme, performed an investigation of the possible use of space for studies in pure and applied plasma physics, in areas not traditionally covered by 'space plasma physics'. A set of experiments have been identified that can potentially provide access to new phenomena and to allow advances in several fields of plasma science. These experiments concern phenomena on a spatial scale (10 1 -10 4 m) intermediate between what is achievable on the ground and the usual solar system plasma observations. Detailed feasibility studies have been performed for three experiments: active magnetic experiments, largescale discharges and long tether-plasma interactions. The perspectives opened by these experiments are discussed for magnetic reconnection, instabilities, MHD turbulence, atomic excited states kinetics, weakly ionized plasmas, plasma diagnostics, artificial auroras and atmospheric studies. The discussion is also supported by results of numerical simulations and estimates.
