Summary

The motion of a charged particle in a magnetic neutral line field and a perpendicular electric field is calculated. Full numerical calculations are performed for parameters relevant to the magnetotail. We consider an acceleration region of length L and height T embedded in the plasma sheet. It is found that for a thin plasma sheet (T = 1000 km) the motion is relatively simple and particles can be energized significantly. For a thick plasma sheet (T = 20,000 km) the motion can be very complicated and particles can actually lose energy. Applications to the magnetotail are discussed.
