AB: A high altitude nuclear detonation could produce an intense artificial radiation belt (RB) of relativistic electrons. Earth satellites operating in this region could be adversely affected. Several concepts have been proposed to remediate the effects of this artificial RB. Among them is the high-voltage electrostatic tether. Preliminary analyses that have been carried out by several groups suggest, that this technique shows promise of controlling the relativistic electron content in artificial RB. The relativistic electron population is one of the most important topics of space weather studies because of its potential damage to civilian and military space assets. There are several fundamental issues that should be examined in order to validate high-voltage tether remediation of artificial RB. Among them are: power consumption, size and stability of the plasma sheath around the tether, and scattering efficiency of the high-voltage system that is related to the plasma sheath size. This study would be focused on the scattering process itself and artificial RB remediation assuming that power consumption and the size of the plasma sheath are known.
