DEVICE FOR REDUCING THE IMPACT OF POSITIVELY CHARGED IONS ON A SURFACE SECTION AND ION ACCELERATOR ARRANGEMENT

摘要

The present invention relates to a surface portion exposed to an ion current, particularly for a drive arrangement of a spacecraft comprising an electrostatic ion accelerator arrangement. According to the present invention, an intermediate potential energy plane is provided for reducing corrosion, and the intermediate potential plane is characterized in that a magnetic field substantially parallel to the surface portion is formed.
