plasma sheet

plasma sheet

[′plaz·mə ‚shēt]
(geophysics)
A region of relatively hot plasma outside the plasmasphere, which reaches, during quiet times, from an altitude of about 30,000 miles (50,000 kilometers) to at least past the moon's orbit in a long tail extending away from the sun; composed of particles with typical thermal energies of 2 to 4 kiloelectronvolts.

The BeroSim software simulates the impact and propagation of heat in laser and plasma sheet metal cutting, which reveals how the heat is distributed and the effect this has on the material.
Several coronal mass ejections have been observed with a superb example occurring on 2011 March 19 when a large plasma sheet was seen extending over the western limb linked by a slender stem.
Interstellar Boundary Explorer (IBEX) designed to image the invisible interactions occurring at the edge of the solar system, has captured the first image of the plasma sheet, a component of the magnetosphere made up of magnetic field lines that attach to the Earth at both ends, bottling up denser plasma (ionized gas), within the magnetotail, the trailing portion of the magnetosphere stretching backwards away from the Sun by the force of the solar wind.
However, a closer look at the various images produced by multiple IBEX orbits revealed what appeared to be a piece of the plasma sheet being bitten off and ejected down the tail.
This is the time when we can expect the moon to cross low-density plasma in the tail lobes and high-temperature plasma in the plasma sheet of the magnetotail (Lichtenstein & Schubert, 1976).
The results for Hypothesis G indicating that retroPK performance might be higher when the moon is moving deeply through the plasma sheet of the magnetotail than when moving through the outer rings of the plasma sheet were significant in the regression analysis of the full moon interval and in the difference of full moon data versus non-full moon data.
Using a satellite called IMAGE (Imager for Magnetopause-to-Aurora Global Exploration), researchers for the first time obtained images of the sun pumping material into its plasma sheet, which is made of highly ionized atoms and pierces Earth's magnetic field.
Rather, the solar-wind plasma mixes with charged particles from the Earth's ionosphere, and some of this mixture makes its way to the plasma sheet, a flat, charge-filled region on Earth's night side that ultimately fuels all auroras.
Here, a plasma sheet is rotated to steer the beam in azimuth and is tilted electronically to steer the beam in elevation.
The plasma sheet can be steered in elevation by tilting the magnetic field, and steering in azimuth may be accomplished by designating cathode initiation sites.
The 5 hour variation appears to be linked to the rotational period of Jupiter's magnetic field and the movement of Ganymede through the tilted plasma sheet that surrounds the planet," said Dr.
It is fed by low-energy charged particles that are lifted into space over Earth's poles, carried behind the Earth in its magnetic tail, but then jerked around 180 degrees by a kink in the magnetic fields that boosts the particles back toward Earth in a region called the plasma sheet.
