Abstract
The ion separation electrodes in isotope separation apparatus are provided with removable collection shields to collect neutral particles which would normally pass through the ionization region. A preferred collection shield comprises a U-shaped section for clipping onto the leading edge of an electrode and a pair of flanges projecting substantially perpendicular to the clipping section for collecting neutral particles.
Claims8
An apparatus for separating an isotopic mixture of the type comprising (a) source means for emitting neutral particles of said isotopic mixture, (b) a plurality of spaced apart electrode means disposed in the path of particle emission;
- (c) in a region between spaced apart electrodes a radiation beam for isotopically selectively ionizing at least some of said neutral particles, said beam occupying less than all of said region, and (d) means for separating said ionized particles from said neutral particles, the improvement comprising:
- at least one collection shield removably engaged to at least one respective electrode having at least one surface projecting from said electrode for collecting those neutral particles from said source which would otherwise pass between electrodes without passing through said beam.
