摘要: A negative ion vessel is divided into an excitation chamber, a ionization chamber and extraction by two magnetic filters. Input means introduces neutral molecules first where electron discharge vibrationally excites the which migrate to second chamber. In ionizes molecules, producing ions are extracted or third filter prevents high energy electrons from entering ionizing An grid at end of attracts accelerates them. Another grid, located adjacent carries small positive voltage in order inhibit migrating contour plasma potential. Additional can be suppressed output flux using ExB forces provided field extractor electric
