Abstract
Magnesium ions were produced by bombarding magnesium vapor by electrons emitted tram oxide coated cathodes. The ions were then focussed into a thin sheet by means of an electrostatic lens. This ion sheet was sent into the magnetic lens which focussed the sheet into a small spot where they were collected. The ion current obtained at the collector was 120 microamperes.
