DEVICE FOR FORMING A QUASI-NEUTRAL BEAM OF OPPOSITELY CHARGED PARTICLES

摘要

A device for forming a quasi-neutral ion-electron beam, including: a chamber; a set of means for forming an ion-electron plasma in the chamber; and means for extracting and accelerating charged particles from the plasma out of the chamber. The particles are capable of forming the beam and the extraction and acceleration means that include a set of at least two grids located at one end of the chamber.
