Abstract
Abstract A tandem ion accelerator is disclosed having a charge reversing device for recharging negative ions into positive ions. The recharging is carried out in a matter-free zone and a light source is provided having a high luminous density for recharging the negative ions into positive ions. Preferably a deflecting device is provided for displacing an ion path and the light source is arranged such that a path of the light emitted from the light source coincides at least with a portion of the ion path.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
101 words
A tandem ion accelerator comprising: (a) an ion source and separator; (b) a high pressure enclosure having a first high voltage acceleration means, a charge reversal means, and a second high voltage accelerator all series connected in the pressure enclosure and receiving ions from the ion source; (c) said charge reversal means comprising means for providing a matter-free zone in which the charge reversal is carried out, light source means having a high luminous density for recharging the ions, and deflecting means for deflecting a path of the ions; and (d) mass separator means connected to the second high voltage accelerator.
