Electron enrichment - of molten metal by electron bombardment

摘要

Electron enrichment by means of a quartz clad induction furnace in which a metal e.g. zinc, copper, iron, is subjected to a high voltage pulse with resultant vapour being extracted by vacuum pumps. A stream of accelerated electrons and protons is injected with the molten metal from a hydrogen/metal pinched plasma. Prior to injection the electron and protons pass through retardation units to reduce their velocity to a level matching that of the thermally excited molten metal electrons to enable orbital electron addn. take place.
