Two-dimensional quiet time equilibrium for the inner plasma sheet protons and magnetic field
نویسندگان
چکیده
In order to study the quiet time proton flow and magnetic field in the inner plasma sheet resulting from electric and magnetic drifts, we incorporate a modified version of the Magnetospheric Specification Model with a modified Tsyganenko 96 magnetic field model to self-consistently simulate plasma sheet protons and magnetic fields with two-dimensional force balance maintained along the midnight meridian. The resulting equatorial proton flows and pressures agree very well with previously published AMPTE/IRM observations quantitatively. Because of this agreement, the simulated forcebalanced magnetic field configuration should give more realistic plasma sheet magnetic field variations for quiet times than does the original T96 model. This 2-D self-consistent simulation is also able to reproduce the observed flows and pressures better than our previous 1-D self-consistent simulation. The improvement results from a more accurate modeling of the coupling between the plasma and the magnetic field in the 2-D self-consistent simulation.

Modeling the inner plasma sheet protons and magnetic field under enhanced convection
In order to understand the evolution of the protons and magnetic field in the inner plasma sheet from quiet to disturbed conditions, we incorporate a modified version of the Magnetospheric Specification Model with a modified version of the Tsyganenko 96 magnetic field model to simulate the protons and magnetic field under an increasing convection electric field with two-dimensional force balanc...
متن کاملModeling the transition of the inner plasma sheet from weak to enhanced convection
[1] We seek to determine whether the adiabatic plasma transport and energization resulting from electric and magnetic drift can quantitatively account for the plasma sheet under weak and enhanced convection observed by Geotail presented in the companion paper [Wang et al., 2004]. We use a modified Magnetospheric Specification Model to simulate the dynamics and distributions of protons originati...

Nowadays, due to the high costs and large dimensions of the conventional proton accelerators, other optimal methods for producing the proton beam have been studied. Using of Laser-driven proton accelerators is one of the important and new methods. In laser-driven ion acceleration, a highly ultra-intense laser pulse interacts with solid density targets and will create a plasma media that will ac...
متن کاملMidnight radial profiles of the quiet and growth-phase plasma sheet: The Geotail observations
[1] To evaluate the plasma sheet transition from weak to strong convection, we investigate ion moments and magnetic field observed by Geotail. The Geotail data from 1995 to 1997 within the area 9 RE XGSM 30 RE and jYGSMj 5 RE were sorted for periods of quiet times and the substorm growth phase, which gives a better indication of convection strength than do global indexes. We find that the overa...
